Allow using file logging with development settings

[AlanCoding]

SUMMARY

I had a headache running integration tests. I found that if you do this:

AWX_LOGGING_MODE=file awx-manage showmigrations

You get a traceback from the logging setup.

bash-5.1$ AWX_LOGGING_MODE=file awx-manage showmigrations
Traceback (most recent call last):
  File "/usr/lib64/python3.9/logging/config.py", line 564, in configure
    handler = self.configure_handler(handlers[name])
  File "/usr/lib64/python3.9/logging/config.py", line 745, in configure_handler
    result = factory(**kwargs)
  File "/usr/lib64/python3.9/logging/handlers.py", line 470, in __init__
    logging.FileHandler.__init__(self, filename, mode=mode,
  File "/usr/lib64/python3.9/logging/__init__.py", line 1146, in __init__
    StreamHandler.__init__(self, self._open())
  File "/usr/lib64/python3.9/logging/__init__.py", line 1175, in _open
    return open(self.baseFilename, self.mode, encoding=self.encoding,
FileNotFoundError: [Errno 2] No such file or directory: '/var/log/tower/cache_clear.log'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/local/bin/awx-manage", line 9, in <module>
    load_entry_point('awx', 'console_scripts', 'awx-manage')()

    raise ValueError('Unable to configure handler '
ValueError: Unable to configure handler 'cache_clear'

This is because /var/log/tower does not exist. The Makefile for this repo (templated) does not pre-create it and the awx user does not have permission to create it.

If you use Ansible to shell into the container and do something, like it's likely that AWX_LOGGING_MODE is unset, which gives the same behavior. So you can't run anything without additional hacks.

There's a good chance that whatever management command you run doesn't write any logs anyway. This is just something I want to increase resiliency and avoid the need for hacks sprinkled around in testing.
