Disable the password edit page

Can we get an option to disable the password page

https://yourdomain.gitlab.com/profile/password/edit

Since we are using SAML, this screen isn’t needed as you can’t sign in with GitLab’s internal password manager. It can be used to access the API, however, this password is currently against our organization's security standards and we would rather just have it disabled. If anyone needs to work with the API, they can use a personal access token.

As an aside, it might also be nice if I could configure and LDAP server for API access when using SAML. Users definitely expect their SAML password to work with the API.
