Previously, when in a panic state, requests would be routed to all
hosts. In some cases it is instead preferable to not route any requests.
Add a configuration option for zone-aware load balancers which switches
from routing to all hosts to no hosts.

The libstdc++ std::regex implementation is not safe in all cases
for user provided input. This change deprecates the used of std::regex
in all user facing paths and introduces a new safe regex matcher with
an explicitly configurable engine, right now limited to Google's re2
regex engine. This is not a drop in replacement for std::regex as all
language features are not supported. As such we will go through a
deprecation period for the old regex engine.

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.

Promote tracing operation field to listener level. This expands the scope of the field to support two use cases:
Tracing TCP connections: istio can send connection events to create a service communication graph. Network filters can benefit from the common knowledge about the intent of the listener/filter chain (client-side vs server-side).
Using ingress/egress designation for other telemetry. The direction of the traffic is a useful label on metrics, and it is not explicit at the moment, unless depending on tracing configuration in HTTP connection manager or naming convention. Both workarounds are not ideal.

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.

this commit bumps protoc-gen-validate to the latest version. this

after this I believe we can also take use of the new address validation
type to fix some unique error messages, but the first step is bumping it

- SocketState was using `.message.required` however it was not
a message type. as far as I can tell this was a bug that PGV fixed.

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).
