Handle errors in DAS records and show them properly on web UI
Add reserved DAS record keys
Switch to use clean_cache
Switch to use status, error, reason in get_status. The status returns status of query processing, while error/reason the possible errors in DAS query
Use json.dumps to print error value; define pval
Move set_misses call inside of write_to_cache; this will allow to properly setup missing keys even if data-service will throw error record
Replaces das_internal_keys with das_record_keys(); added is_error_in_records; add default collection parameter to clean_cache
Now fetch status, error, reason from dasmgr.get_status and use it to setup proper status of returned DAS record
Remove call to set_misses since it is now done in write_to_cache
