afr: support split-brain CLI for replica 3
Ever since we added quorum checks for lookups in afr via commit
bd44d59741bb8c0f5d7a62c5b1094179dd0ce8a4, the split-brain resolution
commands would not work for replica 3 because there would be no
readables for the lookup fop.
The argument was that split-brains do not occur in replica 3 but we do
see (data/metadata) split-brain cases once in a while which indicate that there are
a few bugs/corner cases yet to be discovered and fixed.
Fortunately, commit 8016d51a3bbd410b0b927ed66be50a09574b7982 added
GF_CLIENT_PID_GLFS_HEALD as the pid for all fops made by glfsheal. If we
leverage this and allow lookups in afr when pid is GF_CLIENT_PID_GLFS_HEALD,
split-brain resolution commands will work for replica 3 volumes too.
Likewise, the check is added in shard_lookup as well to permit resolving
split-brains by specifying "/.shard/shard-file.xx" as the file name
(which previously used to fail with EPERM).
