The existing FaultDelay config used uint32 for the percent field which
limited the user to configure percentages only in terms of whole numbers
between 0 and 100. FractionalPercent allows finer control over the
percent values by allowing fractions to be specified in the
configuration, for example 0.0001%.

This change introduces a new configuration parameter for clusters,
`time_between_updates`.
If this is set, all cluster updates — membership changes, metadata
changes on endpoints, or healtcheck state changes — that happen
within a `time_between_updates` duration will be merged and delivered
at once when the duration ends.
This is useful for big clusters (> 1k endpoints) using the subset LB.
Partially addresses https://github.com/envoyproxy/envoy/issues/3929.

Provides a very basic thrift router that can route to clusters
based on method name only. A Thrift DecoderFilter interface is
introduced, but the only available filter is the Router. The
Network filter and router are capable of translating transports
and protocols but presently cannot be configured to do so.
Relates to #2247.

*Docs Changes*: protobuf documentation updated

This patch implements load_assigment field in CDS' Cluster.
This change specifically adds the implementation of the new load_assigment field
for clusters with discovery-type: STATIC, STRICT_DNS and LOGICAL_DNS.
While adding this load_assigment field implementation to Cluster,
this patch also allows specifying optional (active) health check config per specified upstream host.

This is a followup to #3841, where we introduce HCM-wide stream idle timeouts. This has two effects:
1. We can now timeout immediately after stream creation, potentially before receiving request headers and routing.
2. A default timeout can be configured across all routes. This is overridable on a per-route basis.
The default and overriding semantics are explained in the docs. Also added as a bonus some docs
about how timeouts interact more generally in Envoy.
Fixes#3853.
Risk Level: Low. While there is some change to the per-route vs. HCM wide semantics for stream idle
timeouts, it's not anticipated this feature is in common use yet (it's only a couple of days since
landing), and the caveats in #3841 with the new 5 minute default timeout should already apply.
Testing: Unit/integration tests added.

Some sites where we consume HeaderValue, e.g. in Google gRPC client library metadata, require
non-empty keys as a precondition. This seems a general property; there shouldn't be any use case for
a header key that is empty.
Found with server_fuzz_test under oss-fuzz (issue 9373). As a bonus, also fixed another proto
descriptor crash that occurs with this corpus addition due to missing proto descriptor pool entries
in server_fuzz_test.

This PR avoids a situation in which we were losing track of data plane requests as follows:
1. Management server asks Envoy to track load stats for cluster Foo in a LoadStatsResponse for a 10s period. Envoy resets stats for Foo.
2. After the 10s timer, Envoy responds with Foo's stats, resetting them.
3. Management server asks Envoy to track load stats for cluster Foo in a LoadStatsResponse for a 10s period. Envoy resets stats for Foo.
4. After the 10s timer, Envoy responds with Foo's stats, resetting them.
Between 2 and 3, any stats for Foo requests that arrive were previously unaccounted for. We resolve
this (in a relatively backward compatible way) by not making any protocol changes except to require
Envoy to not reset stats for already tracked clusters.
If we were to design LRS from scratch to avoid this, there are better approaches, e.g. making it a
periodic reporting service rather than request-response, but we probably already have a bunch of
existing users of LRS and don't want to break them.

This is the complete HTTP/1.1 implementation of #3301, new style websockets.
