The `dsa` message replies to a `dsq` message and allows the user to join
a mixing pool.
The `dsa` message allows a node to join a mixing pool. A collateral fee is
required and may be forfeited if the client acts maliciously. The message
operates in two ways:
1. When sent to a masternode without a current mixing queue, it initiates the
start of a new mixing queue
2. When sent to a masternode with a current mixing queue, it attempts to join the
existing queue
Dash Core starts a new queue ~33% of the time and attempts to join an existing
queue the remainder of the time.
