features: add a directory-protection translator
This is useful to find all calls that remove a file from the protected
directory, including renames and internal calls. Such calls will cause
a stack trace to be logged. There's a filter script to add the needed
translators, and then the new functionality can be invoked with one of
the following commands.
setfattr -n trusted.glusterfs.protect -v log $dir
setfattr -n trusted.glusterfs.protect -v reject $dir
setfattr -n trusted.glusterfs.protect -v anything_else $dir
The first logs calls, but still allows them. The second rejects them
with EPERM. The third turns off protection for that directory.
