Describe the bug:
In range queries autocomplete suggesting wrong value for time_zone field
"time_zone": "+1:00".
This value of time_zone will lead to illegal_argument_exception

Steps to reproduce:

1. In Dev Tools create range query.
2. Start to type "time_zone"
3. Press TAB when autocomplete suggest

Expected behavior:
Time_zone should insert value in format HH:MM
Example:
"time_zone": "+01:00".
Provide logs and/or server output (if relevant):
{ "error": { "root_cause": [ { "type": "illegal_argument_exception", "reason": "java.time.DateTimeException: Invalid ID for ZoneOffset, non numeric characters found: +1:00" } ], "type": "illegal_argument_exception", "reason": "java.time.DateTimeException: Invalid ID for ZoneOffset, non numeric characters found: +1:00", "caused_by": { "type": "date_time_exception", "reason": "Invalid ID for ZoneOffset, non numeric characters found: +1:00" } }, "status": 400 }
