UI - CLI - Account Policy Plugin missing functionality

[droideck]

Issue Description
We need to be able to set State Attribute to a non_existen_attr.
Also, there's no way to add configuration entry with the data like this (which later can be used for CoS config) using UI and CLI:

dn: cn=Account Inactivation Policy,dc=example,dc=com

objectClass: top
objectClass: ldapsubentry
objectClass: extensibleObject
objectClass: accountpolicy
accountInactivityLimit: 2592000
cn: Account Inactivation Policy

And dsidm account entry-status should be adjusted accordingly to the new feature - #5749
