Support using paramiko to set up accelerate connection

Adds original_transport attribute to Runner to track what the original
transport was before it is changed to 'accelerate'.
If using paramiko in original_transport, uses ParamikoConnection.  If
not, falls back to SSHConnection like before.
Expand tilde in paths in file module
Added remote_user to plays

Still compatible with user: but deprecating it so we can have
a matching remote_user: in tasks, cannot be user: because of the
module of the same name. #3932

Locate easy_install path after (optionally) creating virtualenv.

Without this, the first call to the easy_install module with a new virtualenv
will only create the virtualenv without installing the intended package, since
the `_is_package_installed` check will succeed as running /usr/bin/easy_install
as non-root user will return permission denied error with empty stdout.
Fix for update-rc.d based systems that also have systemd installed

By default, the service module had assumed that if the system had the
update-rc.d binary, the service was either managed via upstart or standard
sysV init-style scripts. This patch adds a check for systemctl ahead
of the other methods when update-rc.d is detected, and also simplifies
the logic around the detection of systemctl-managed services
Minor fix to account for template service names in systemctl
Fix to getchanged correctly for yum groupinstall.
Add an example for installing a group with the yum module.
Check for systemd ownership of a service even if an init.d script exists

Also slight modification to the error message in the earlier commit that
modified the update-rc.d detection portion of the code

Remove YAML inventory example.
Slight refactorization of the sysctl module

* Added in support for freebsd-style sysctl commands
* Replaced some functionality that was provided by module_common
* Simplified some logic in a couple of places (ie, not checking
  a split with len() but instead limiting the split to 1)

Allow service module to manage services not ending in .service
