Currently, the reading of config related to promisor remotes is done in
two places: once in setup.c (which sets the global variable
repository_format_partial_clone, to be read by the code in
promisor-remote.c), and once in promisor-remote.c. This means that care
must be taken to ensure that repository_format_partial_clone is set
before any code in promisor-remote.c accesses it.
To simplify the code, move all such config reading to promisor-remote.c.
By doing this, it will be easier to see when
repository_format_partial_clone is written and, thus, to reason about
the code. This will be especially helpful in a subsequent commit, which
modifies this code.
