Add force recovery sequence

I want force sequence recovery for client session. May be need special parameter in configuration section for this?

```
-    else
-      throw InvalidMsgSequence(seqnum, _next_receive_seq);
+    //else //corrected
+    //  throw InvalidMsgSequence(seqnum, _next_receive_seq);
```

When sending GenerateSequenceReset, sequence for this message must be set to BeginSeqNo from ResendRequest message.

```
-      send(generate_sequence_reset(rctx._interrupted_seqnum, true));
+     send(generate_sequence_reset(rctx._interrupted_seqnum, true), rctx._begin);
```

FYI i use process model coroutine

```
-      f8_scoped_spin_lock guard(_per_spl);
+      //f8_scoped_spin_lock guard(_per_spl);//corrected
//locking with 
Session::send_process(...)
{
.....
   if (_persist)
   {
     f8_scoped_spin_lock guard(_per_spl);
    .....
    }
    ......
}
