* cmd/uplink: add share command to restrict an api key
This commit is an early bit of work to just implement restricting
macaroon api keys from the command line. It does not convert
api keys to be macaroons in general.
It also does not apply the path restriction caveats appropriately
yet because it does not encrypt them.
* cmd/uplink: fix path encryption for shares
It should now properly encrypt the path prefixes when adding
caveats to a macaroon.
* fix up linting problems
* print summary of caveat and require iso8601
* make clone part more clear
What: This change moves project-level bucket metadata encryption information to the volatile section, because it is unlikely to remain in future releases
Why: Ultimately, the web user interface will allow bucket management (creation, removal, etc), but not object management as that requires an encryption key for sure and we don't want to have users give the satellite their encryption keys.
At a high level, a (*Project) type should map to all of the things you can do inside the web user interface within a project, which by necessity cannot have an encryption key. So, we really don't want an encryption key in the non-volatile section of this library.
