Being able to set static version for `docker` package

[mhkarimi1383]

We need to set static version of docker for lots of reasons, if it's okay I will make a PR ;)

I have done some investigations, we can set that in package name followed by - for yum and for apt we use package name followed by =

since we set have our package name configured like below

docker_edition: 'ce'
docker_package: "docker-{{ docker_edition }}"
docker_package_state: present

I don't know if it's okay to overwrite it directly or making tasks more conditional to handle new variable for version

You could just set docker_package to the exact package. Making it work with =/- so it works across multiple distros can be quite tricky, so for the limited number of users who do need to pin a version, I recommend they do that by overriding the package variable itself.
