Remove TODO: the play already overrides options

Show a better message when ansible.cfg is not found

Earlier we would say «Using  as config file» if we didn't find one.

Split py24 testing into its own tox section

Another small batch of trivial FIXME removals

In particular, fix arg parsing

Fixes #11820

Fixes for synchronize with delegate_to

Only run win_feature tests when the host has the ServerManager module.

Add an option for PowerShell modules to indicate support for check mode, skip running module if check mode is not supported.

- Add support for inserting module args into PowerShell modules.  Fixes #11661.
- Support Windows paths containing spaces.  Applies changes from #10727 to v2.  Fixes #9999.  Should also fix ansible/ansible-modules-core#944 and ansible/ansible-modules-core#1007.
- Change how execution policy is set for running remote scripts.  Applies changes from #11092 to v2.  Also fixes ansible/ansible-modules-core#1776.
- Use codepage 65001 (UTF-8) for WinRM connection instead of default (CP437), convert command to UTF-8 and results from UTF-8.  Replaces changes from #10024.  Fixes #11198.
- Close WinRM connection when task completes.
- Use win_stat, win_file and win_copy modules instead of stat, file and copy when called from within other action plugins (only when using WinRM+PowerShell).
- Unquote Windows path arguments before passing to win_stat, win_file, win_copy and slurp modules (only when using WinRM/PowerShell).
- Check for win_ping module to determine if core modules are missing (only when using WinRM/PowerShell).
- Add stdout_lines to result from running low level commands (so stdout_lines is available when using raw/script).
- Update copy action plugin to use shell functions for joining paths and checking for trailing slash.
- Update fetch action plugin to unquote source path when using Windows paths.
- Add win_copy and win_template action plugins that inherit from copy and template.
- Support running .bat and .cmd scripts using default system encoding instead of UTF-8.
- Always send PowerShell commands as base64-encoded blobs to allow for running simple PowerShell commands via raw.
- Support running modules on Windows with interpreters other than PowerShell.
- Update integration tests to support above changes and test unicode fixes.
- Add test for win_user error from ansible/ansible-modules-core#1241 (fixed by ansible/ansible-modules-core#1774).
- Add test for additional win_stat output values (implemented by ansible/ansible-modules-core#1473).
- Add test for OS architecture and name from setup.ps1 (implemented by ansible/ansible-modules-core#1100).

All WinRM integration tests pass for me with these changes.
