fetch: allow adding a filter after initial clone
Retroactively adding a filter can be useful for existing shallow clones as
they allow users to see earlier change histories without downloading all
git objects in a regular --unshallow fetch.
Without this patch, users can make a clone partial by editing the
repository configuration to convert the remote into a promisor, like:
git config core.repositoryFormatVersion 1
git config extensions.partialClone origin
git fetch --unshallow --filter=blob:none origin
Since the hard part of making this work is already in place and such
edits can be error-prone, teach Git to perform the required configuration
change automatically instead.
Note that this change does not modify the existing git behavior which
recognizes setting extensions.partialClone without changing
repositoryFormatVersion.
