(MODULES-910) Convert @apache_version to a string

Three part version numbers cannot be floats and must
be represented as strings. This commit changes all instances
of $apache_version and any comparsions to use strings and the
versioncmp function.

This also fixes comparsion of Float and String errors with future
parser enabled.

Add fcgid options

This adds fcgid.conf to configure the fcgid module. It also adds the
FcgidWrapper option to vhost's directories.

The vhost option lacks any validation and allows users to shoot
themselves in the foot, but without iteration from the puppet future
parser I don't see a way to add the validation. Iteration would also
allow auto including apache::mod::fcgid.
