MDEV-4911 - add KILL query id, and add query id information to processlist

Browse Source 
It is now possible to kill query by query id. KILL syntax was extended to:
KILL [HARD | SOFT] [CONNECTION | QUERY [ID query_id]] [thread_id | USER user_name]

Added QUERY_ID column to INFORMATION_SCHEMA.PROCESSLIST.

Fixed tests affected by this change:
- added PROCESSLIST.QUERY_ID column
- ID is now keyword and is quoted in SHOW CREATE TABLE output
- PFS statement digest is calculated basing on token id
  (not token text). Token id has shifted for keywords residing
  after ID in keywords array.
