templates: add match function
Add a match function that returns true if a string matches the provided
regular expression. The compiled regular expressions are cached in
a sync.Map to avoid repetitive compilations of the same expressions.
Caveat: if the user mixes the arguments order, it may cause the cache to
consume a lot of memory filled with garbage regular expression objects.
Ideally, we would need to limit the size of this cache and/or use a LRU
cache implementation. Maybe someday?
