[ML] Add a timeout option to file structure finder (#34117)
This can be used to restrict the amount of CPU a single structure finder request can use. The timeout is not implemented precisely, so requests may run for slightly longer than the timeout before aborting. The default is 25 seconds, which is a little below Kibana's default timeout of 30 seconds for calls to Elasticsearch APIs.

If you recognize more fields than the simple `grok_pattern` produced by the

advanced `grok_pattern` as a query parameter and the structure finder will

calculate `field_stats` for your additional fields.

`\[%{TIMESTAMP_ISO8601:timestamp}\]\[%{LOGLEVEL:loglevel} *\]\[%{JAVACLASS:class} *\] \[%{HOSTNAME:node}\] %{JAVALOGMESSAGE:message}`.
