v2 Avoids ssh Runtime error

Prevents trailing zeros to be truncated from strings in hosts ini inventory variables

Prevents an exception from raising in some corner cases where SSH might
be misconfigured. It seems not to fix a specific problem, although it
makes the method a little bit more solid.

Pulls machine id in ansible facts

- Fix #10221

changed jsonify test to ignore whitespace

We have been caching the paths to the plugins but before we would only
cache the specific plugin that we were looking for.  This meant that we
might search through all of the plugin directories before finding the
specific module we were interested in.  The next plugin we needed we
might again search through all the plugin directories before finding the
plugin we wanted.

This new code will cache all the potential plugins in each directory
searched.  For a play that only uses one plugin we'll only search
through directories until we encounter the directory that has the proper
plugin.  For a large playbook with many plugins used we'll search
through each directory at most once each.
