Extend SQL syntax for searchable encryption

[Zhaars]

Extension syntax for searchable encryption to support INSERT/UPDATE/DELETE syntax as we did in PR with searchable tokenization

P.S. Also, during integration testing, I noticed that a lot of raw bytes were printed in the output. Changed the logging fields just to print packet type instead of raw bytes slice.
