Simple version of patterned_text with a single doc value for arguments (#129292)

Browse source 
Initial version of patterned_text mapper. Behaves similarly to match_only_text. This version uses a single SortedSetDocValues for a template and another for arguments. It splits the message by delimiters, the classifies a token as an argument if it contains a digit. All arguments are concatenated and inserted as a single doc value. A single inverted index is used, without positions. Phrase queries are still possible, using the SourceConfirmedTextQuery, but are not fast.
