TODO:

  * Done - If adding 'A' record type for any already exists 'name', check if there is already any entry for 'name' with any other 'A' record, if found
  print "WARNING: '%s' record for '%s', already found with different content value!" % (type, name, content)

  If adding 'CNAME' record, validate the CNAME 'content' record is present with 'A' record, if not exit with message.
  print "WARNING: '%s' record for '%s', doesn't have any 'A' record value!" % (type, name)

  * Done -  Validate given 'name', which can be accepted with FQDN (with zone) or simple HOSTNAME
  (we need to add .zone.com after hostname if not found)

  If deleting 'A' record, check and remove if there are any 'CNAME' records with that 'A' records.

  Add activity event records to log file and to database.

  Find and List all broken records, those are not resolve from your zones/domains

  Replace record type 'A' to 'CNAME'
    Condition match found: If adding 'A' record, and the IP already assinged to another hostname, warn and ask to user
    > Do you want to add cname against the match found or continue
    If yes, add record to cname, if no go with what your wants
    add/delete (if it found any existing record set for that content)

  If deleting record 'anytype' (without giving -c content), if match result more than one,
    ask user to provide input Y/N , to delete entire match found.

  Search wildcard or nearest match while showing search result.

  Replace 'insert' with 'update' sql statement in zone2sql

  Add zone with base template

  Adding record type 'A' also adds the reverse PTR for ..
