Copy Module: Add the ability to set directory attributes on recursive copy.
Merge pull request #1 from bcoca/stat_updaates

added octal representation of mode and made md5 checksumming optional
Replace mode with octal renaming to mode.

Closes GH-6176

This way for mode we return in an octal format which is immediately usable compared to transforming it later.
Typo fix.
Merge pull request #6221 from risaacson/pull_6176

stat module: mode is now returned as an octal and md5 call can be skipped.
Fully clean 'ssh_old' and 'paramiko_alt' options

These transports have been removed in 33857855ad6d358d56d5fe60bd49be653b247e0b
Typo in rabbitmq_plugin docs

Should be "plugins", not "users".
Use the no-user-groups option (-N) for useradd in the user module

If no group was specified, but a group by the same name as the user
exists, an error was raised in the situation where USERGROUPS_ENAB is
enabled in /etc/login.defs (which is the case for almost every major
linux distro). In this case, the user will be put in group 100 (which
is usually the "users" group on those same distros). This is currently
only done in the base class, as the issue may not exist on other
platforms like AIX or the BSDs.

Fixes #6210
Support ssh-ed25519 keys

The newest version of OpenSSH supports a new, wonderful key type. authorized_key incorrectly discards pubkeys of this type as busted because it doesn't recognize type signature.
