22f57cd84e Add timeout to clientaccess http client 
The default http client does not have an overall request timeout, so
connections to misbehaving or unavailable servers can stall for an
excessive amount of time. At the moment, just attempting to join
an unavailable cluster takes 2 minutes and 40 seconds to timeout.

Resolve that by setting a reasonable request timeout.

1acb25d884 Fix managed etcd cold startup deadlock issue #2249 
We should ignore --token and --server if the managed database is initialized,
just like we ignore --cluster-init. If the user wants to join a new
cluster, or rejoin a cluster after --cluster-reset, they need to delete
the database. This a cleaner way to prevent deadlocking on quorum loss,
and removes the requirement that the target of the --server argument
must be online before already joined nodes can start.

289ba8df6a All arguments should be of the form --k=v so that bool flags will work 
Previously a bool flag would be rendered as --flag false for `flag: false`
which is invalid and results in the opposite of what you'd expect.
