* services: un-mark group services as deregistered if restart hook runs
This PR may fix a bug where group services will never be deregistered if the
group undergoes a task restart.
* e2e: add test case for restart and deregister group service
* cl: add cl
* e2e: add wait for service list call
* services: always set deregister flag after deregistration of group
This PR fixes a bug where the group service hook's deregister flag was
not set in some cases, causing the hook to attempt deregistrations twice
during job updates (alloc replacement).
In the tests ... we used to assert on the wrong behvior (remove twice) which
has now been corrected to assert we remove only once.
This bug was "silent" in the Consul provider world because the error logs for
double deregistration only show up in Consul logs; with the Nomad provider the
error logs are in the Nomad agent logs.
* services: cleanup group service hook tests
* nsd: block on removal of services
This PR uses a WaitGroup to ensure workload removals are complete
before returning from ServiceRegistrationHandler.RemoveWorkload of
the nomad service provider. The de-registration of individual services
still occurs asynchrously, but we must block on the parent removal
call so that we do not race with further operations on the same set
of services - e.g. in the case of a task restart where we de-register
and then re-register the services in quick succession.
Fixes#15032
* nsd: add e2e test for initial failing check and restart
This PR adds support for specifying checks in services registered to
the built-in nomad service provider.
Currently only HTTP and TCP checks are supported, though more types
could be added later.
