* **Other Changes**
  * chore: update g-c-cpp-common to v0.25.0 (#1458)
  * feat: provide a mockable `Clock` class (#1452)

I would remove this, changes in internal should not be interesting.

  * feat: provide a mockable `Clock` class (#1452)

  * feat: allow for the emulator in ClientIntegrationTest.QueryOptionsWork (#1453)
  * docs: add snippets for methods and classes in keys.h (#1451)

I do not think the users care about this.

  * cleanup: eliminate an unnecessary local variable (#1450)
  * doc: add mention of GOOGLE_CLOUD_CPP_TRACING_OPTIONS env var (#1448)

Ditto.

  * chore: remove some unncessary NOLINTs (#1447)
  * ci: use build cache for ci/kokoro/docker builds (#1446)

Same thing.

Same here.

  * test: reduce running time of SessionPool.SessionRefresh (16s to 2s) (#1445)

  * feat: add overloads to admin connections for specifying policies (#1439)
