JMX To Prom Exporter - More Inclusive Table Naming Regex

# The Issue

For our company usecase, we actually use UUIDs for our table names. Ex: cfec8068-c04e-4131-8c29-1e4850b5c015_OFFLINE

However, the current JMX Prom Java agent config looks like below:

```
- pattern: "\"org.apache.pinot.common.metrics\"<>(\\w+)"
name: "pinot_controller_segmentsInErrorState_$3"
cache: true
labels:
table: "$1"
tableType: "$2"
```

`w+` unfortunately does not encapsulate the `-` in the table name, therefore causing us to lose metrics for all of these tables as it fails the regex. This in turn means we can't have proper alerts for bad segment and unavailable states.

## The Proposal

PR incoming but effectively changing all instances of `((\w+)_(\\w+)` to `(\\S+)_(\\w+)`. In this way, it will accept all non-whitespace characters as a valid name for a table. I do understand that Pinot has exceptions on using `.` in table names, but APIs will cleanse / ensure those table names are sanitized to w/e standard. Hence, if a table name is guaranteed to be clean, it should be properly exported and why I suggest the more flexible regex.

Start by locating the JMX Prom Java agent configuration entries containing the shown segmentsInErrorState pattern and identify every matching table-name regex. Verify the current behavior with a UUID-based table name, update the relevant patterns to accept the intended non-whitespace names, and confirm that the corresponding metrics and labels are exported.
