  rtpengine: remove rtpengine probing from SIP procs

Probing is now done exclusively by timer workers and by `rtpengine_reload` mi command.

  rtpengine: enhancement of set/node management

This commit has several enhancements:
1. Introduce reload types via MI command `rtpengine_reload type=soft|hard`.
  - Hard reload: all nodes are disconnected and all sockets are rebuilt per process. This is the default behavior, and is the behavior that existed before this commit.
  - Soft reload: nodes stored in the database are compared (based on URL) to nodes stored in memory. If the node exists in memory, then the existing node is reused (including all sockets and disabled state). If the node does not exist in memory, then it is added to the set and sockets are built per process. Remaining nodes are removed from the set and sockets are destroyed, as they have no associated database record.
2. Introduce version history for shared set list. This is needed after allowing soft reloads to prevent race conditions, as sockets are maintained per process while the set list is maintained in shared memory.
3. During a `rtpengine_reload`, the write lock is released before probing nodes.  Depending on the set size and node status, probing can be a timely task. By releasing the write lock, we free up the SIP procs to access the shared set list.
