BetweenDateRegex generate a regex to filter mysql error log dates to just get events between 2 dates Currently limited to filter by day to produce "short" regexes.

IsNodeUUID can only try to see if that's an UUID functionally, it could also be a "regexNodeHash", but it's indistinguishable from wsrep_node_name as it won't have any specific format.

basically capturing anything that does not have a date needed, else we would miss some logs, like wsrep recovery.

SetVerbosity accepts any LogRegex Some can be useful to construct context, but we can choose not to display them.

5.5 date : 151027 6:02:49 5.6 date : 2019-07-17 07:16:375.7 date : 2019-07-17T15:16:37.123456Z5.7 date : 2019-07-17T15:16:37.123456+01:00 10.3 date: 2019-07-15 7:32:25.
