http: allow custom index-pack args

Browse Source 
Currently, when fetching, packfiles referenced by URIs are run through
index-pack without any arguments other than --stdin and --keep, no
matter what arguments are used for the packfile that is inline in the
fetch response. As a preparation for ensuring that all packs (whether
inline or not) use the same index-pack arguments, teach the http
subsystem to allow custom index-pack arguments.

http-fetch has been updated to use the new API. For now, it passes
--keep alone instead of --keep with a process ID, but this is only
temporary because http-fetch itself will be taught to accept index-pack
parameters (instead of using a hardcoded constant) in a subsequent
commit.
