Allow global and per user setting to disable password changes

[jmalenaatxactly]

Is your feature request related to a problem? Please describe.

Would like to disable the ability for all users, or specific users to not be able to modify their passwords. There may be circumstances where an account is shared and one person changes the password, while the other person who shares the same account does not have the updated password and now they don't have access anymore.

Describe the solution you'd like

Under the user section, there could be a setting like so:

{
  "users": {
    "allow_password_change": false
  }
}

Or if you want to do it at a user level, it can be defined as such:

{
  "users": [
    {
      "username": "exampleuser1",
      "allow_password_change": false
    },
    {
      "username": "exampleuser2",
      "allow_password_change": false
    }
  ]
}

Unless defined, the default is true. The global setting sets all accounts to false, while the user specific setting disables password changes to only those accounts specified, all other accounts are set to true.

Describe alternatives you've considered

Disabling access to the WebUI, but I want users to be able to access the WebUI, but not have the ability to change passwords.
