This adds a new google.protobuf.Timestamp last_updated field to BootstrapConfigDump, ListenersConfigDump, ClustersConfigDump, and RoutesConfigDump, representing the time when the configs under that category were last updated.
Additionally, the ProdSystemTimeSource::instance_ singleton is passed through several layers of interfaces. This is to make testing easier, but I would love to find a workaround for injecting a MockSystemTimeSource closer to the point where it is needed in the tests.
Risk Level: Low
Testing:
Several tests were modified / updated to compare the dumped time (always 1234567890 seconds since epoch time) by using a MockSystemTimeSource which always returned 1234567890.

This change does several things:
1) Clarifies how we handle xDS version_info in responses and sets us up
for both top-level/transactional versions as well as per-resource
versions in the future.
2) Moves the config_dump admin endpoint to the v2alpha namespace so that
we can iterate on it in the future.
3) Fills out the config dump proto for the remaining resource types.
These are not implemented but are here to force a discussion about
how we want to handle versions moving forward.
4) Fixes RDS static config dump to actually work and add better tests.
5) Wire up version for the RDS config dump on a per-resource basis.
Once we agree on the general version semantics I will be following up
with dump capability of the remaining resource types.
