localrepo: remove unused requirements attributes on localpeer (API) The previous changeset removed the last consumer of requirements. I'm not sure when supportedformats became unused. But I couldn't find any obvious instances where it is being used. It likely stems from peers being derived from repository instances several years ago and is a holdover from that day.

exchange: access requirements on repo instead of peer As part of formalizing the peer interface, I audited for attribute accesses for non-internal names to find API violations. This uncovered the code changed in this commit. localpeer.requirements is just an alias to the repo's requirements attribute. So, change the code to get the data from the source instead of relying on a one-off attribute in the localpeer type. Differential Revision: https://phab.mercurial-scm.org/D265
