hs-v3: Add a public function to upload a descriptor to an HSDir

This is groundwork for the HSPOST control port command that needs a way in the
HS subsystem to upload a service descriptor to a specific HSDir.

To do so, we add a public function that takes a series of parameters including
a fully encoded descriptor and initiate a directory request to a specific
routerstatut_t object.

It is for now not used but should be, in future commit, by the HSPOST command.
This commit has no behavior change, only refactoring.
