The jid will now also contain the PID of the async_wrapper process,
and can each unique jid from each host is tracked rather than just
relying on one global jid per task.

Fixes #5582

Because async_wrapper subtracts 5 from time_limit and checks for
equality to zero, values not divisible by 5 will go negative and
continue forever.

whitespace + remove deprecated YAML parser (migration script lives in examples/scripts and warning was added
in 0.6 release)

Add encoding lines to python modules such that they can take unicode options if they are fed them, since the
AnsibleModule stuff no longer base64 encodes for simplicity and speed reasons.

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.

It wasn't killing the job at all before.
Indentation was 3 spaces.

Eliminate possible race condition in async_wrapper where ansible deletes the argsfile while the module
is still kicking off.  Should not happen except in modules that are somewhat slow to load and probably
can be fixed better than the included sleep, i.e. some IPC communication that the process has
launched and is ok to exit.  This works pretty well for now though.

Fix async to use the new argfiles method (wrapping brain around rock, really must write module development guide)

is not letting async_wrapper daemonize itself when it does work fine when directly executed.

still needs to daemonize.  Then, once done, playbook can be taught how to poll async within the
timing window.
