This change adds a pair of histograms to track timeout budget usage: one for the

such that 100% of the timeout budget is a value of 10000 so that four digits of

Introduce new fallback policy for subset load balancer's selectors: KEYS_SUBSET and related LbSubsetSelector config parameter: fallback_keys_subset.
When context metadata matches given selector on keys, but there is no matching subset and KEYS_SUBSET fallback policy is set for that selector, there will be another attempt on subset selector matching. For that consecutive attempt, the context metadata will be reduced to keys included in fallback_keys_subset.

Modifies the pedantic spell checker to better handle camel-case words.
Each part the word is now treated as a separate error in both the check
and fix modes.
Disables run-together mode for aspell, which allowed typos such as
"mananger" (man + anger). Fixes the resulting spelling errors.
Miscellaneous other fixes:
* Provides an option to replace a word without adding the word to the
dictionary (in case aspell's suggestions do not contain the correct
replacement).
* Fixes a bug in the script when no suggestions are returned by aspell.
* Checks the dictionary and added words for invalid characters that cause
aspell errors at dictionary load time.
* Sets the mark flag when in CI runs so that misspelled words are indicated.
* Culls words from the dictionary that are no longer in the codebase, or are
otherwise not needed.

API for #8016
Customers adopting service mesh likes mTLS ability. However, rolling it out without breaking existing traffic is hard. This is because mTLS is configured on per cluster basis. In reality, a service consists of multiple endpoints, mixed with having Envoy sidecar and without-sidecar endpoints. Client envoy can't send mTLS traffic until all server migrated to having Envoy sidecar.
This API tries to solve the issue by allowing mTLS/transport socket to configured at finer granularity, e.g. endpoint level. The endpoint has metadata label information, which will be used to decide which transport socket configuration to use from a map specified in the cluster.
So the outcome is that, xDS management server is able to configure client envoy talks to endpoints with sidecar in mTLS and plain text to endpoints without sidecar, for a single cluster.

This patch introduces a new tool, protoxform, that will be the basis of
the v2 -> v3 migration tooling. It operates as a Python protoc plugin,
within the same framework as protodoc, and provides the ability to
operate on protoc AST input and generate proto output.
As a first step, the tool is applied reflexively on v2, and functions as
a formatting tool. In later patches, this will be added to
check_format/fix_format scripts and CI.

Depending on the execution environment in which envoy is being run, it
is possible that some of the assumption on the clock are maybe not
holding as previously commented. With some sandboxing technologies the
clock does not reference the machine boot time but the sandbox boot
time. This invalidates the assumtpion that the first update in the
cluster_manager will most likely fall out of the windows and ends up
showing a non intuitive behavior difficult to catch.
This PR simply adds a comment that will allow the reader to consider
this option while reading to the code.

Due to a seg fault issue with the gogo protobuf library
[https://github.com/gogo/protobuf/issues/568], non nullable repeated
fields in a proto will cause proto.Merge(dst, src) to panic.
The nullable field setting was first added by @kyessenov when he was
re-organizing the protos. Unfortunately, people have been copy pasting it
across several areas in the Envoy proto. To keep the impact radius to a minimum,
I have updated only the fields that are currently causing the segfault
(in go-control-plane) for us.
Its also partly against proto principles. You should be able to determine if
a field is set or not. This non-nullable setting in gogo will insist on initializing
the field to default values.

Currently, in load_balancer_impl.cc: recalculatePerPriorityPanic(), even if common_lb_config.healthy_panic_threshold is 0%, a load balancer enters panic mode whenever normalized_total_availability is 0%.
I guess, a user who intentionally set to healthy_panic_threshold = 0 expects to immediately return error responses if there is no available host checked by a load balancer.
(In fact, current load_balancer_impl.cc: isGlobalPanic() decide not to enter panic mode whenever healthy_panic_threshold is 0%.)
So I suggest that panic mode is disabled only when healthy_panic_threshold is 0%.
I want this change for automatic degenerating lower priority or optional back-end services.
Risk Level: Low
(It seems that setting healthy_panic_threshold == 0 is a special case originally. It won't happen unless a user intend to disable panic mode, because default value of healthy_panic_threshold is 50%.)

This makes it possible to configure the subset LB to match metadata
match criterias with any of the values specified in a list value on an
endpoint. This allows endpoints to have multiple values for a given
metadata key.
To accomplish this the invariants of the subset trie construction
changed: a host can now be associated with multiple subsets for a set of
subset selectors. To support this the trie construction had to change to
traverse all possible paths for each host.

This code change allows to redefine fallback policy per specific subset selector. Because of how existing LbSubsetMap trie data structure is organised (mapping subset key to values), is not possible to do lookups for fallback policy only based on subset keys (had to introduce additional trie that maps subset keys to keys and has fallback policy on leaf level). Additional LbSubsetSelectorFallbackPolicy enum required to correctly identify the case when fallback policy is not set for given selector (otherwise it would always default to NO_FALLBACK, breaking backwards compatibility, if field is not set we should use top level fallback policy instead).

This adds an option to allow hosts to be excluded in lb calculations until they have been health checked
for the first time. This will make it possible to scale up the number of hosts quickly (ie large increase
relative to current host set size) without triggering panic mode/spillover (as long as the initial health check
is succeeds).
While these hosts are excluded from the lb calculations, they are still eligible for routing when panic
mode is triggered.
