Redirect Yard command line warnings to a log file called `.yardwarns`.
Yard warnings may be irrelevant, spurious, or may not conform with our
styling and UX design. They are also printed on stdout by default.
Due to the changes in PUP-3900 which renamed Puppetx to PuppetX
and puppetx to puppet_x, strings was failing since the namespace
had not been updated in strings. In order to be compatible with this
change, update strings by renaming the namespace to match.
In order to ensure strings is still compatible with earlier versions
of puppet that don't include the namespace change, declare our own
PuppetX module. This way, if it is an older version and the namespace
is called Puppetx, the necessary PuppetX namespace will be created.
