the main goal of this change is to make `make docker-isolated` work out
of the box
- specify the proper version for awx-expect --version
- update some deprecated playbook bits
- change the isolated container to privileged so bwrap will work
- fix awx-manage test_isolated_connection
- expedite the first isolated heartbeat so you don't have to wait 10m;
this is accomplished by _not_ setting Instance.last_isolated_check to
now() at insertion time (which causes the next check not to happen for
10 minutes)
- fix a bug that caused isolated node execution to fail when bwrap was
enabled

This reverts commit 9863fe71dcaa987ed28d70ac6873ece058344ab3.
This moves the container-based code location and venvs.
The goal here is that the paths of Tower source for isolated
vs normal nodes matches (both in prod and local development) so that we
don't have to add a bunch of additional bwrap argument logic for
<location-of-isolated-tower-venv>.
