* received at the same time), so we perform a kind of state machine here. We are concerned with two events: knowing
* the token associated with an endpoint, and knowing its operation mode. Nodes can start in either bootstrap or
* normal mode, and from bootstrap mode can change mode to normal. A node in bootstrap mode needs to have
* pendingranges set in TokenMetadata; a node in normal mode should instead be part of the token ring.
*
* Normal progression of ApplicationState.STATUS values for a node should be like this:
* STATUS_BOOTSTRAPPING,token
* if bootstrapping. stays this way until all files are received.
* STATUS_NORMAL,token
* ready to serve reads and writes.
* STATUS_LEAVING,token
* get ready to leave the cluster as part of a decommission
* STATUS_LEFT,token
* set after decommission is completed.
*
* Other STATUS values that may be seen (possibly anywhere in the normal progression):
* STATUS_MOVING,newtoken
* set if node is currently moving to a new token in the ring
* REMOVING_TOKEN,deadtoken
* set if the node is dead and is being removed by its REMOVAL_COORDINATOR
* REMOVED_TOKEN,deadtoken
* set if the node is dead and has been removed by its REMOVAL_COORDINATOR
*
* Note: Any time a node state changes from STATUS_NORMAL, it will not be visible to new nodes. So it follows that
* you should never bootstrap a new node during a removenode, decommission or move.
