HomedirMethods::MountEx was converting MountParameters to MountRequest proto.
To simplify this, remove MountParameters and use MountRequest everywhere.

- Construct MountRequest directly in MountEx's caller sites.
- Rename FillKeyProtobuf() in homedir_methods.cc to
KeyDefinitionToKey(), and make it public.
