Enable imports to work on a snippet based system, allowing for instance a library of common EC2 functions
to be reused between modules.  See library/system/service and library/system/ping for initial examples.  Can
work the old way to just import 'basic', or can import the new way to import multiple pieces of code from
module_utils/.

When service module is used on unsupported Linux system where init
script is used directly, LinuxService.svc_cmd is None so .endswith()
fails.

This extends fix from e2f20db5 also
for state=restarted.

Fixes issue #3533

Fixes #3417

Fixes #3615
Fixes #3572

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

Fixes #3474

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

Fixes #3556

sleep option for service module which adds a pauze between stopping and starting a service using state=restarted. This helps for bad scripts that exist immediatly after signaling a process to stop.

Some services have a knob (i.e. rc.conf setting) whose name
differs from that of the script. For example, lockd process
is controlled with a script called lockd, but the rc.conf
value is rpc_lockd_enable.

Fixes issue #3382.

Syntax like "'foo' if bar else 'baz'" is not supported by all Python
versions targetted by Ansible. Hence we break it up.

When update-rc.d is used to enable/disable service, the changed flag was
always true (see #2189). This commit fixes that.
