Add sip2json pvar

[vladpaiu]

Summary
Add sip2json pvar

Details
Needed for cases when you want to pass a generic SIP message to a SIP agnostic entity, but still want to provide some layer of SIP parsing before sending the full message further.

Solution
JSON with First line, Headers and Body

Compatibility
Backwards compatible

Special Thanks to Voicenter for sponsoring the work.

Thank you @vladpaiu . Here is some feedback:

"Must" changes:

• this function should not be part of the core, but rather some module, maybe cfgutils or sipmsgops (even better)
• documentation is needed, describing the json structure

"Nice to have" change:

• for the body sections, it would be nicer to have an array of body parts, to also deal with the multi-part body. The array will have all the time at least one part (if there are no multi-parts) and each array element will consist of an element containing an optional Content-Type field and the mandatory body part itself.

If you consider converting this pvar into a function, you may also parametrize it - like an optional parameter with white/black filters to control the headers to be added into JSON.

Now, on second thoughts, I see a better option to have this functionality as function in sipmsgops module.

Any updates here? No progress has been made in the last 30 days, marking as stale.

@vladpaiu, any chances to get the MUST changes (at least) by tomorrow, so we can include this into the 3.5 release on 9th ?

moved the implementation to sipmsgops and added documentation

Thank you @vladpaiu - could you add couple of words in the doc about the format of the resulting json? is it like one node per line? or ? Thanks !
O will merge as soon as the CI tests are validated.
