We no longer need to translate the arguments of manage_db.sh into
arguments for alembic. The new facade script for alembic (db.sh)
accesses the alembic api programmatically.
This is consistent with other similar pairs of files:
[script-name].sh invoking scripts/[script-name].py (check_model, create_roolshed_db, db)
Also, the python file does not require exec permissions.
For ToolShed, we have create_toolshed_db.sh.
For galaxy and toolshed install databases (gxy and tsi branches under
alembic), we use the `init` subcommand of the `db.sh` script (`./db.sh
init`), which has exactly the same functionality as these deleted
scripts.
To the best of my knowledge, these are not used anywhere else (unlike,
for example, scripts/manage_db.py, which is called from the
ansible-galaxy role).
1. Remove aliases from subcommands that change things (upgrade, downgrade,
revision, init) to reduce risk of accidental usage.
2. Add aliases to readonly subcommands (history, show, version,
dbversion)
3. Minor edits
Rationale: alternate config file applies to all subcommands, so, I
think, it is more correct to run this:
> ./db.sh -c mygalaxy.yml upgrade some-revision-id
than this:
> ./db.sh upgrade some-revision-id -c mygalaxy.yml
That's also consistent with how alembic handles this option.
instead of directly loading it as YAML.
Will make it easier to uniformly deal with changes of format (e.g.
we are deprecating ini now).
