--------------------------+----------------------------
 Using the WP_Term_Query, caches are generated using the args passed to the
 class instance. However, there are a number of params passed, that would
 not affect the cache but would create a new cache key. Couple of example
 of these are.

 - pad_counts
 - update_term_meta_cache

 These params can be removed from the cache key with no affect to cache.

 There are other params such as slug and term_taxonomy_id, that can be both
 string and array. If all these were convert to arrays, it would improve
 the likelyhood that would be a cache hit.

 There are likely more wins to be had to improve caches here.
