Rebuild Replica fails when using MaxScale encrypted password for Monitor

Rebuild Replica fails when using MaxScale encrypted password for Monitor.

If you use the following Monitor configuration using an encrypted password

[Monitor]

type=monitor

module=mariadbmon

servers=ub01,ub01g

user=mxs_user

password=53183D571DCCDBC5E9A8D68267D7CBE5290B3D07BCE65A98F1B53

ssh_user=msa

ssh_keyfile=/tmp/id_rsa

ssh_check_host_key=off

When you try to rebuild a replica, on the source node the mariabackup command is sent the encrypted password value, causing the process to fail.

If you use the below Monitor configuration when you try to rebuild a replica, it sends the plain text password, and this let's the mariabackup command succeed

[Monitor]

type=monitor

module=mariadbmon

servers=db1,db2

user=m_user

password=plain_text_password

ssh_user=msa

ssh_keyfile=/tmp/id_rsa

ssh_check_host_key=off

Can we allow for encrypted passwords to be used for the Rebuild Replica process and have the correct version (plain text) sent to the mariabackup?
