The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked.  I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
    shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.

running and to report errors from starting them

_find_binaries now sets the right globals
Binaries are now properly populated (reverse path/binary for loops)

Checks if update-rc.d (Ubuntu) or chkconfig (RHEL) should be used.
Adds basic bin path search for those binaries
Adds 'enable' and 'disable' options for 'enable' command since it's the
arguments that update-rc.d uses (this might be somewhat confusing to
have a command line with 'enable=enable', but probably mkes sense for
Ubuntu users).
Allows use of mixed case for 'list' and 'state' commands.

make it useful from /usr/bin/ansible and the API.  Also some minor style fixes.

When running the service module via sudo, `$PATH` didn't contain `/sbin`,
so the service binary couldn't be found.  This just runs `/sbin/service`
directly.  Output is spewed to stderr on error.

Added `list=status` to include the output of `service <cmd> status`.

all modules take a common parameter name.  But more or less we still work idempotently
in modules.

module vs command module for restarting.  May be some bugs and requires the service to implement 'status' -- and probably some better error handling (i.e. return JSON with "failed" element if failed).

Improvements welcome.
