Although there is a version check for docker-py, it still can fail in
the case of downgrading docker-py (e.g. when going to `prod` from
`dev`):

CommandExecutionError: Error 404: client and server don't have same version (client : 1.19, server: 1.18)
TEST CASE:
- Install docker-py 1.4.0
- Have a state to downgrade it
docker-py:
pip.installed:
- name: docker-py==1.2.2
- require:
- pkg: python-pip
- reload_modules: true
dockerng will be loaded, but then cause the above 404 errors.
This can be fixed by using `version=auto` for the `docker.Client`, which
could also be provided in the Salt config (`docker.version`).
The support for `version=auto` has been added in docker-py 1.1.0.
When using an invalid gitfs configuration parameter, the following error
happened:
[CRITICAL] Invalid gitfs configuration parameter 'foo' in remote https://example.com/. Valid parameters are: base, mountpoint, root, ssl_verify, name.
[ERROR ] An un-handled exception was caught by salt's global exception handler:

- expected return type of pkg.latest was changed without updating zypper module
- unchecked list deref fixed
- "zypper info -t" out-of-date status field format has changed
Without this change, any OrderedDict instances in our minion_opts (in
this case from grains) would be serialized to a format that
yaml.safe_load couldn't load. Configuration parsing would error out.
This was preventing the docs for this module from getting built. I'm not
sure how or if that can be mocked using our normal docs Mock() system.
It may be better to use Salt's loader to build the docs rather than
mocking imports. Needs experimentation...
