[399306] [Security] Add password management

https://bugs.eclipse.org/bugs/show_bug.cgi?id=399306

Initial implementation of Change Password:

  - client->server request to initiate password change
  - server->client request to change password, implemented
     via the Diffie-Hellman key agreement utility
  - optional API for pluggable credentials providers to provide
     updates to the user's credentials
  - updated default interactive credentials provider to use a
     new CredentialsUpdateDialog to get a new password from
     the user (with implicit authentication)
