rDENV2a5d9a2776dd: Simplify the scheduler's database initialization

Summary

Use the new "init-admin" command to initialize the database and fallback to the standard postgresql initialization.
The database creation is delegated to the postgresql entrypoint, the extensions and the tables are configured respectively by the init-admin and init commands.

Using this, we can execute the "init-admin" command at each start which can be useful when new super-user migrations are added.

Example of a restart:

swh-scheduler_1                 | Creating extensions...
swh-scheduler_1                 | psql:/srv/softwareheritage/venv/lib/python3.7/site-packages/swh/scheduler/sql/10-superuser-init.sql:1: NOTICE:  extension "uuid-ossp" already exists, skipping
swh-scheduler_1                 | Initializing the database...
swh-scheduler_1                 | DONE database for scheduler exists at version 17
swh-scheduler_1                 | Starting the swh-scheduler API server

This is a poc for the scheduler, all the databases initialization could be changed this way when the diff on swh-core will land.
