fbrnch clone is not equivalent with fedpkg clone

[LecrisUT]

The differences I've found so far:

• fedpkg clone populates a .git/hooks/pre-push

  #!/bin/bash
  
  # This file was generated by fedpkg when cloning the repository.
  # You can edit it to your liking or delete completely. It will not
  # be recreated.
  # Creating this file can be also prevented by adding an option
  # "skip_hooks = True" into the fedpkg's config file; [fedpkg] section.
  
  _remote="$1"
  _url="$2"
  
  exit_code=0
  while read -r _local_ref local_sha _remote_ref _remote_sha
  do
      command -v fedpkg >/dev/null 2>&1 || { echo >&2 "Warning: 'fedpkg' is missing, \
  pre-push check is omitted. See .git/hooks/pre-push"; exit 0; }
      fedpkg pre-push-check "$local_sha"
      ret_code=$?
      if [ $ret_code -ne 0 ] && [ $exit_code -eq 0 ]; then
          exit_code=$ret_code
      fi
  done
  
  exit $exit_code

• fedpkg clone populates a .git/info/exclude

  i386/
  i686/
  x86_64/
  ppc/
  ppc64/
  ia64/
  mips/
  arm/
  noarch/
  /*.src.rpm
  /build*.log
  /.build-*.log
  results/
  results_*/
  clog
  

• fedpkg sets up some additional git-configs, but these might be skipped.

          helper = /usr/bin/fedpkg gitcred
          useHttpPath = true
  [bz]
          default-tracker = bugzilla.redhat.com
          default-product = Fedora
          default-version = rawhide
          default-component = rust-logos

I think it would be useful to synchronize it as much as possible because the user might be switching from one tool to the other, and artifacts from fedpkg srpm/mockbuild would not be nicely ignored.
