Note that automating this test is challenging, and I believe this should be tackled separately. |

@okraport should this be backported to v17 as well? |

There was a problem hiding this comment.
Keep in mind that this is not a guarantee that we can connect, if the cache is also unhealthy or has failed to initialize and connectivity to auth is down we'll still error out when getting CAs.

Yes, thank you for pointing that out. Added the label. |
This change allows the agent dialer to use cached
results for hostCheckerFunc. In the case of a transient
grpc network failure, this allows the reverse tunnel
to be re-established before the grpc timeout takes place.
Test plan:
- [ ] Spawn two Linux VMs, one for auth/proxy and one for node.
Simulate network change by toggling one of two interfaces on the node,
measure time for the reverse tunnel to be functional again.
In local testing with 5 runs this on average brings the recovery time
to 2m39s from 3m45s.
Changelog: Improve reverse tunnel dialing recovery from default route changes by 1min on average.
