Allow dialplan ID to identify a ruleset to be a string

Is your feature request related to a problem? Please describe.
It can be difficult remembering which dialplan ruleset does which thing, because the dpid field is an integer. When editing the rules in the database, the same applies. If you have many rules, you have to remember which number means which thing.

Describe the solution you'd like
I think it would be handy to be able to apply names to dialplan rulesets as it would be more intuitive. If dialplan.dpid could be a string, then I could for example create a ruleset that I could refer to as "uk_local_to_e164" instead of "7".

Implementation

• Component: dialplan module
• Type: module's parameter
• Name: same as it is now, just allow a string

Describe alternatives you've considered
No alternatives.

Comment from Bogdan: "Indeed, it may be an interesting one. And as Ben said, we are also using M4 for the scripting, nevertheless, if you want to integrate with OpenSIPS Control Panel, it may become tricky ;)"
