fix(backup): convert odoo regex extensions

[yajo]

The backup image accepts a regexp on DBS_TO_INCLUDE. But Odoo uses a regexp with custom extensions (%h and %d).

If you use any of those extensions, the backup jobrunner will fail with CalledProcessError.

Additionally, regexps usually contain a $ symbol, which needs to be escaped for docker-compose.

BREAKING CHANGE: if your dbfilter contained $$ previously, to do that escaping yourself, you will have to convert it to a single $

Puedes hacer rebase para ver si te sale ya CI en verde?

Still with error. Maybe it's provoked by this PR.

Other builds pass green, and the one that fails says:

ERROR: for smtp  toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
Traceback (most recent call last):
  File "/usr/local/bin/build", line 26, in <module>
    subprocess.check_call(["docker-compose", "pull", *services_to_pull])
  File "/usr/local/lib/python3.9/subprocess.py", line 373, in check_call
    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['docker-compose', 'pull', 'db', 'smtp']' returned non-zero exit status 1.

So it seems like you'll have to add credentials to authenticate with docker hub and thus increase the free pull limits. Or just retry until it passes.

Please, rebase and let's see if the CI error gets fixed.

I think this is ready to merge @pedrobaeza
