0.3.4(yanked): regression config expansion no longer happens

[ssbarnea]

Apparently last release no longer works with configuration items that have expansions as they endup being used directly:

  msg: 'Error pulling image molecule_local/${MOLECULE_IMAGE:-centos:7} - 400 Client Error for http+docker://ssh/v1.41/images/create?tag=7%7D&fromImage=molecule_local%2F%24%7BMOLECULE_IMAGE: Bad Request ("invalid reference format: repository name must be lowercase")'

The previous one 0.3.3 does not have the same bug. Until we fix it, please add molecule-docker!=0.3.4 to your dependencies.

Bisecting I was able to identify that this regression was introduced by #51

Apparently there are other issues with newer release. I seen error below with ansible 2.9.22, which was not expected:

msg: the connection plugin 'community.docker.docker' was not found

That is caused by #56 as 'community.docker is not installed by it

The big question is if we want to enforce use of 'community.docker collection or if we want to fallback to the older docker module included with ansible 2.9

For that second problem the workaround is to run ansible-galaxy collection install community.docker

I yanked 0.3.4 release and due to the huge number of changes needed the next release will be 0.4.0 and we will not make any fixes to the current one (being unable to test them correctly).
