Remove tantivy dependency from quickwit-common

[fmassot]

I introduced this dependency in #2116 but we want to keep quickwit-common as light as possible.

I believe we can move that in the quickwit-doc-mapper but I was not very fond of it. The advantage is that tantivy is already use there.

I'm going to close this because #2205 is also adding a dependency on tantivy.

I can remove the deps to tantivy in #2205.

I just removed this deps, and I confirm it would be nicer to remove tantivy from quickwit-common.
