🐛 Add input text box filtering in new tag's select a tag category field (#1919)

Resolves RFE https://issues.redhat.com/browse/MTA-1248

User selecting a tag category from the drop-down should also be able to
insert the input text. Instead of scrolling down and selecting from the
long list would be very much convenient for user to enter the text and
matching string gets filtered.
