MT#22185 Fix ngcp-sync-grants/-constants, use 'pair' MySQL DB instead of 'local'

On Carrier:
local mysql is 127.0.0.1:3308
 pair mysql is localhost:3306

On CE/PRO:
local mysql is localhost:3306
 pair mysql is localhost:3306

ngcp-sync-grants/-constants should use pair mysql to upload grants/passwords.
local mysql is comming from db01:3306 using ngcp-sync-db.
