Converted Apache::TS::AdminClient to use Dist::Zilla

Converted the perl module to use Dist::Zilla in preparation for updated release on CPAN. The current version is 0.03 which I figure is a little old.

The removal of some of the files is because Dist::Zilla automagically recreates them on release.

# VERSION is also replaced by 'our $VERSION = X.X.X' on Dist::Zilla build.
