This commit refactors the tap transport socket to use the common
tap extension configuration and tap matching infrastructure. More
match conditions will be added in a future PR as well as additional
cleanups that have been marked with TODOs.
One result of this PR is that the HTTP tap filter can now have a static
configuration as well as write to a file per tap sink.
All future tap PRs should be smaller and more targeted after this one.

This is a rename PR only. It renames the capture transport socket
and associated tools to the tap transport socket. It also updates
some documentation. In a subsequent PR I'm going to refactor the
tap transport socket to use the new common tap framework so that
the tap transport socket can be configured via admin, the HTTP
tap filter can write to a file, the tap transport socket can have
matching, etc.

Fixes https://github.com/envoyproxy/envoy/issues/743
This is a general cleanup of all of the access logging documentation.
I have reorganized a bunch of things and hidden the various gRPC logging
fields that are not implemented yet.
I've also moved the existing tap protos into a new "output" directory. This
is the best name I could come up for cleanly separating output data that might
be stored outside of any service or configuration.

* tap/fuzz: transport socket extension for traffic capture.
This PR introduces a transport socket extension that wraps a given transport socket, interposes on its
plain text traffic and records it into a proto trace file on the filesystem. This can be used for a
number of purposes:
1. As a corpus for fuzzing the data plane.
2. Converted to PCAP using a soon-to-be-written utility, allowing existing tools such as Wireshark
to be used to decode L4/L7 protocol history in the trace. Essentially this lets us take advantage
of the PCAP ecosystem.
Relates to #1413 and #508.
Risk Level: Low (opt-in).
Testing: New SSL integration tests, demonstrating plain text intercept.

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.

This PR follows thru on https://github.com/envoyproxy/envoy/issues/1873
on the data-plane-api side.
Also, update the Python validation script and added a test to ensure
this is captured in CI to avoid future bit rot.

This tool will take a LDS response message with holes where opaque
filter configs should go, and fill them with the Struct equivalent of
the protos supplied for the filter configs. It emits both output
text proto and JSON.
To generate example output listeners.pb and listeners.json, run bazel
build //examples/service_envoy:listeners_files.
