* fix: Proxy closing listener with 0 connections left
A bug was introduced in `0.15.0` where sessions with max connection counts were closed when the connections left hit 0. This issue was highlighted by a user: https://github.com/hashicorp/boundary/issues/4364. What was happening was when we have zero connections left the proxy code was closing the listener which closed its connections
To fix this:
- `boundary connect -target-id=xx -host-id=xx` command with no connections left will now wait for all connections to be closed and before exiting the session just like it did in `0.14.3`
- As soon as there are no more connections left, the listener will close to stop accepting new connections
- Fix issue where the websocket connection was throwing closing errors during the session teardown.
This allows arbitrary programs to have an easy mechanism to make
connections through Boundary using Go. Internal cluster tests and test
helpers have been migrated to use this package, as well as the `connect`
command.
