This adds two new config options for the `database` stanza:
- `max_idle_connections`
- `max_idle_time`
These correspond to settings for the underlying `sql.DB` instance. They
can be used to have finer control over the controller's database
connection pool. For example this can be used to mitigate the high
connection overhead when connecting to postgres by setting a high
`max_idle_connections` and either setting `max_idle_time` to zero or to
a high duration.
Alternatively, if using a connection pool like pgpool-II or pgbouncer,
`max_idle_connections` can be set to 0.

* feat(controller): New health service and server
This change also implements a new listener purpose, `ops`.
`ops` (short for operations) is a new listener purpose that is
responsible for serving Boundary's operations endpoints, like health
and possibly metrics.
At Startup: `ops` listeners get configured as late as possible to catch
any errors with the startup process;
At Shutdown: If the health endpoint has been set-up, we introduce a
configurable delay in the process. This is to enable the health endpoint
to report unhealthy for that amount of time. `ops` listeners are also
the last listeners to be shutdown.
