the help message on forms is not usefull.

We should rename it to update the administrator hacluster user password. (Used by pacemaker cluster and HAWK webui)
Something similar.

@gao-yan afaik where the hacluster user is used right?

1) this values is pretty much sensible.

we should make the password field to the TOP and make the user by default changing the password instead of having it falling back to the default which can be weak password.

Also the position of the form should be on the 1st position or on the top level since it is important
