hg: pass command intents to repo/peer creation (API)
The previous commit introduced a mechanism to declare command intents.
This commit changes the repository and peer instantiation mechanism
so the intents are passed down to each repository and peer type so
they can do with them whatever they please.
Currently, nobody does anything with any intent.
