[sr-dev] [kamailio/kamailio] async: added support for millisecond resolution sleep (#2016)

[Paweł Pierścionek]

#### Type Of Change
- [X] New feature (non-breaking change which adds new functionality)

#### Checklist:
- [ ] PR should be backported to stable branches
- [X] Tested changes locally

#### Description
- new ms_timer parameter to enable millisecond precision timer
- new async_ms_route and async_ms_sleep functions with milliseconds as a param
- implementation:
  Each async_ms_sleep adds an entry to a linked list sorted by expiry time.
  List is checked every ms_timer ms for expired entries.
  All expired entries are pushed for execution on a pool of async workers.

This allows easy implementation of request traffic shaping with an external leaky bucket microservice
Assuring a maximum rate with no dropped requests by introducing delay.
