When a module is in place to provide documentation for an action, it should be allowed to have a doc string.

Without a docstring users of pydocstring will need to suppress:

```
************* Module plugins.modules.git_away
plugins/modules/git_away.py:1:0: C0114: Missing module docstring (missing-module-docstring)
************* Module plugins.modules.git_here
plugins/modules/git_here.py:1:0: C0114: Missing module docstring (missing-module-docstring)
```

With a doc string the module is treated as a "real" module and fails sanity:

```
ansible-module-not-initialized: Execution of the module did not result in initialization of AnsibleModule
```

PEP257 suggests modules should have a docstring, and is generally considered a good practice to inform future developers of the purpose of the file and can be used for documentation generation as well.
