chore: remove ssh background config (#97)

From my testing, Toolbox forwards through SSH (i.e. through Coder) a
remote port associated with the IDE
running in server mode, to localhost in order for the server (i.e. the
remote IDE) to communicate with
JBClient. Unlike with Gateway, Toolbox manages to reuse the SSH
connection, and it doesn't open a separate
one for port forwarding.

From Gateway we inherited two ssh hostnames per each workspace, one for
background connections that did not
involve running IDEs. Coder discards the bg. connection from the
collected metrics in order to
avoid double counting. Since Toolbox manages to re-use the connection we
don't need to worry
about double counting.

For this particular change, I deployed the latest Coder version with
prometheus metrics and experiments
enabled (i.e. --prometheus-enable --prometheus-collect-agent-stats
--experiments=workspace-usage) and made the following experiment:

1. Opened up Toolbox, logged into Coder. At this point:
- agent_sessions_total and coderd_agentstats_session_count_jetbrains
were missing from prometheus metrics
- jetbrains session count from api/v2/deployment/stats showed 0

2. Opened up a Workspace at which point Toolbox established the SSH
connection:
- agent_sessions_total and coderd_agentstats_session_count_jetbrains
increased to 1
- jetbrains session count from api/v2/deployment/stats increased to 1 as
well

3. Hit the install button on RustRover, everything stayed unchanged

4. Open RustRover, nothing changes in the stats.
