This commit modifies the script
`deploy/build_env/services-linux/run_asapo.sh` so that we can use it
to deploy services compiled in a directory other than `build/`. This is
very convenient during development on a local machine  because we may
want to store different build flavors in directories under the `build/`
directory.

Note: if no directory is passed to the script, the script uses the
`build/` directory by default.

Use different version of discovery config for tests and standalone. Standalone version should be accessible from different nodes.

Add components to run standalone asapo service inside of build_env container. This should help to run integration tests.
