This was previously deprecated and we received no feedback to keep it
in.
I also updated the podman python binding to the newly active name.

* Fix file logging level issue.

Fixes #223

* Patch awx logging to allow trace logging in all cases.

* added optional label support

* provider/container - support labels, skip envars as labels

* label formatting logic moved to commands.py

* labels arg renamed to provider-labels

* labels - AT provider - fix label value parsing

* add provider_label support to execute command

* fix provider_labels parsing for container provider

* provider_labels are nested for AT provider

* append label asserts to test_container_e2e

* Add parsing of eventual settings.provider_labels for AT, Container providers

* add e2e provider_labels fn test for AA

Instead of wrapping everything under a single ProviderError, let's add
some nuance.

This change fills the gap previously seen for podman's inability execute
commands on containers.
A large part of this was handling the returned output from podman's
exec_run, which is a tuple containing the return code and a bytes string
containing both the stdout and stderr.
Due to this, we needed to implement a demuxer.

Also made some minor tweaks to the functional tests

There are cases, like github actions, where it is preferable for
broker's settings to come from a local repo clone than from github.
This change starts with a check for the local clone with a fallback to
the source on github.

* Add foreman broker

* add example settings for Foreman broker

* Reorganize classes

- Rename ForemanAPI to ForemanBind
- Put Foreman Bind in a separate file
- Create exception for FormanBind
- Make internal method private
- Add method to query hostgroup information

* Apply organizational changes in tests too

* Get rid of constructor call in provider_help

* Hotfix for github action
