[FEATURE] Disable Reset Password (#823)

* [FEATURE] Disable Reset Password
* add configuration key to authentication_backend called disable_reset_password
* disable_reset_password prevents the API handler for the functionality and the UI element
* disable_reset_password is a boolean
* adjust RememberMeEnabled to be RememberMe instead as it's just unnecessary
* add docs for security measures and in the authentication docs
* updated config.template.yml
* add flexEnd style to align reset password when remember me disabled
* add todo items for ldap user/password validation relating to this
