[DOCS] key rejection is not mentioned in the guides when AES key rotation situations happens

Description Is not obvious that key rejection causes AES rotation for publications.

The Salt Master generates a new AES key to encrypt its publications at certain events such as a Master restart or the removal of a Minion key. If you are encountering this problem of too many minions re-authing against the Master, you will need to recalibrate your setup to reduce the rate of events like a Master restart or Minion key removal (salt-key -d).

The Salt Master generates a new AES key to encrypt its publications at certain events such as a Master restart or the removal/rejection of a Minion key. If you are encountering this problem of too many minions re-authing against the Master, you will need to recalibrate your setup to reduce the rate of events like a Master restart, Minion key removal (salt-key -d) or Minion key rejection (salt-key -r).

A rotating AES key is used to encrypt jobs that are sent to the Salt minion by the Salt master, and to encrypt connections to the Salt master fileserver. A new key is generated and used each time the Salt master restarts and each time a Salt minion key is deleted using the salt-key command.
