Review comment:
Make this `PositiveLongValidator` since timeout of 0 does not make sense.
Maximum value can be `Integer.MAX_VALUE`

> Make the timeout in TimedCallable a configurable boot time parameter

> Key: DRILL-7223
> URL: https://issues.apache.org/jira/browse/DRILL-7223
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.16.0
> Reporter: Aman Sinha
> Assignee: Boaz Ben-Zvi
> Priority: Minor
> Fix For: 1.17.0

> The
> [TimedCallable.TIMEOUT_PER_RUNNABLE_IN_MSECS|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/store/TimedCallable.java#L52]
> is currently an internal Drill constant defined as 15 secs. This has been
> there from day 1 of the introduction. Drill's TimedCallable implements the
> Java concurrency's Callable interface to create timed threads. It is used by
> the REFRESH METADATA command which creates multiple threads on the Foreman
> node to gather Parquet metadata to build the metadata cache.
> Depending on the load on the system or for very large scale number of parquet
> files (millions) it is possible to exceed this timeout. While the exact root
> cause of exceeding the timeout is being investigated, it makes sense to make
> this timeout a configurable parameter to aid with large scale testing. This
> JIRA is to make this a configurable bootstrapping option in the
> drill-override.
