v2 api changes: Use oneof to specify header match options, based on value(exact_match), regex or range.
The existing value and regex fields will be deprecated. Use the header_match_specfier oneof instead.
Add a new range.proto (envoy.type.v2) for the range type definition.
The SInt64Range message is defined in envoy.type.v2 range.proto.
It consists of start and end (inclusive, exclusive) sint64 values.
v1 api: Add a range_match object to the route headers json. Presence of this object indicates range based route match.
Example: For the below route config:
{
"prefix": "/",
"cluster": "PartitionB",
"name": "PartitionKey",
"range_match": { "start": 0, "end": 10}
}
In the incoming request, if the PartitionKey header value = 0, route match succeeds. Route match fails if the header value = 10, -10, "somestring".
This feature can be used for request routing with Service Fabric stateful services, to route to the desired partition with the [ranged partitioning scheme](https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-concepts-partitioning#ranged-partitioning-scheme)

There are several main changes in this PR:
Create envoy.api.v2.core packages to break circular dependencies from xDS on to subpackages on to base protos.
Create individual packages for each filter and add independent versioning to each filter.
Add visibility constraints to prevent formation of dependency cycles.
Add gogoproto annotations to improve go code generation.
After moving xDS service definitions and top-level resource protos back to envoy.core.api.v2, cycles were created, since the second-level definitions depend on base protobuf definitions, and are in turn included from xDS; however xDS and base definitions are in the same package.
The solution is to split the base protos into another package, envoy.api.v2.core. That eliminates dependency cycles (validated using go-control-plane).
Added a few gogoproto annotations to improve golang code generation.
