Nadav Har'El be969ff995 alternator: add find_tag() function ...

find_tag() returns the value of a specific tag on a table, or nothing if
it doesn't exist. Unlike the existing get_tags_of_table() above, if the
table is missing the tags extension (e.g., is not an Alternator table)
it's not an error - we return nothing, as in the case that tags exist
but not this tag.
