Do not clear cli config on logout

If we do this, users will just be forced to provide credentials all over
again when they reconnect to a workspace from this deployment, say from
the recents menu or from just reopening VS Code.

Since the only way to have multiple deployments right now is to log out
of one then log into the other, it seems like this will just cause more
needless work.

Possibly we should instead allow logging in if already logged in (maybe
call it "switch deployment") to support adding a new deployment without
logging out first, and then show a warning while logging out, but for
now do this.  This matches the JetBrains plugin behavior, at least.

Can revisit when adding support for listing multiple deployments at a
time.
