Add recommended extension installation support
Extensions on recommended installation list will be automatically installed just like forced installed extensions, but are allowed to be disabled (not allowed to be uninstalled).
This CL adds a new ExternalLoader for recommended extension (use EXTERNAL_PREF_DOWNLOAD as location), another MustRemainInstalled() function to interface of ManagementPolicy, and related WebUI changes.
