This PR starts to plumb multiple TLS certs from the proto level into the SSL context. We stop short
of enabling multiple TLS certificates, but instead have sufficient mechanism and interface changes
to propagate them to the SSL context. Future PRs will extend this with the SSL context

Adds an option that allows smoothing out the locality weights when used
with subset lb: weights are scaled by the number of hosts that were
removed due to the subset filter. This allows for less of a step

Currently health check failure events are only log if the HealthFlag for a host transition from non-FAILED_ACTIVE_HC to FAILED_ACTIVE_HC. However, since hosts are initialized in the FAILED_ACTIVE_HC state, hosts that never became healthy have no events associated with it.
Since the current health check events only log transitions, we'll have to scan the entire log in order to find the hosts in a current failing state. Then we'll still have to filter the hosts permanently removed from the cluster by the discovery service. This makes the events very difficult to use in operations.
Proposed solution
Both of these 2 issues can be solved by emitting a health check failure event if either of these conditions are true:
If the active health check failed and it's the first health check for a host. This ensures we have events for hosts that never became healthy.
If the active health check failed and a AlwaysLogFailures configuration is set to true, by default this flag is set to false. This makes it very easy to find the hosts currently failing by looking at the last few seconds of logs.

This commit enables the configuration of the mapping that translates 429
response code to a gRPC status code. By default, the Rate Limit filter
in Envoy translates a 429 HTTP response code to UNAVAILABLE as specified
in the gRPC mapping document. Google, however, recommends translating a
429 response to RESOURCE_EXHAUSTED. This commit provides a flag named
rate_limited_as_resource_exhausted in the RateLimit config which allows
users to explicitly specify whether they want 429 responses to be mapped
to RESOURCE_EXHAUSTED, while UNAVAILABLE remains the default.

This fixes a bug in the other priority plugin that would cause a crash
when retries were attempted when the upstream had no healthy hosts. The
existing check for no healthy was ineffective due to the "everything is
terrible" fallback in the LoadBalancerBase which sets P0 to 100 when all
the priorities are unhealthy.
The fix is to check for healthy % based on the loads computed in the
plugin, not the ones returned by LoadBalancerBase. When all hosts are
unhealthy, we return the original priority load. This ensures that we
maintain whatever fallback the default LB uses when there are no
unhealthy hosts.

Add a new config option under access_log called json_format. This is a single level dictionary that contains strings as keys, and envoy access log format specifiers (such as %PROTOCOL%) as values.
The specifiers will be replaced with actual values at logging time. I call this dictionary the "format dictionary" (as opposed to "format string").
You can specify only one of format (format string) or json_format (format dictionary). If neither are there, we fall back to the default string format.
Add the correct plumbing inside the configuration parsing to handle this.
Add a new access log formatter class that is instantiated with the format dictionary. It maintains the mapping of dictionary keys to loggers
Create a new class called FormatterProvider, to distinguish things that actually extract the information from a request. The things that combine together a bunch of FormatterProviders are still called Formatters. This is primarily a semantic/naming difference, but imo these are two conceptually separate things. There is, however no API difference, and if people are truly opposed to this, I could just merge them back into one Formatter class. This also provides a better foundation for adding more log formats in the future.
At present, only one specifier per key in the format dictionary is allowed. This is because the whole point of JSON logging is to make logs easily machine-parseable. If you can include multiple formats in the same field, then you'll be right back to parsing those manually
At present, only top-level keys are allowed in the format dictionary. This is validated at config load time. In the future, we can expand this to have nested dictionaries.
Risk Level: Low. It's an optional feature that has to be explicitly enabled.
Testing: Unit testing for the actual formatter, and config load. Also manually tested using an example config file.
Docs:
Amended Access Log docs to create a notion of "Format Strings" and "Format Dictionaries".
Put things that are common to access logs in general under "Format Rules", and then distinguished how strings and dictionaries are different.
Called out restrictions on format dictionaries
Added protobuf comments for format and json_format
