    Force redis::ulimit to be an integer

    The upstream change at:
    https://github.com/voxpupuli/puppet-redis/commit/502ff38c8c035fa143e32dd4ee61b3ec68db461c

    made redis::ulimit an integer and will now error out if passed a string.
    Historically in THT we passed RedisFDLimit directly to the redis::ulimit
    hiera key as a string. Let's just change RedisFDLimit to a number. The
    only affected people will be those that A) tweaked this parameter and
    B) actually wrapped the param into quotes so to force it as a string.
    Given that this number is likely non-significance, we choose this route
    and we avoid an extra YAQL invocation to do a conversion in THT.
