[FEATURE] Add setting to whether allow user account change IP themself

[hstan77]

Is your feature request related to a problem? Please describe.
Current interface do not limit User account to change IP, All user account are allow to change IP themselves. This may not be issue if NAT customer , where all is their own Lan IP and they can change themselves.
However if GuestSharedNetwork and SecurityGroup Isolation where Public IP is the GuestNetwork IP, this will create issue where User Account can change their IP themselves without Administrator Permission.

Thus, I suggest to add Setting in Accounts, to allow / disallow the User Change IP themselves.
