fuse/md-cache: add support for the 'fopen-keep-cache' mount option
fopen-keep-cache disables unconditional page-cache invalidations on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that behavior with detection of remote changes and explicit invalidations from mount/fuse. This option improves local caching through the page cache and native client. This change defines a new 'invalidate' translator callback to identify when an inode's cache mapping has been determined to be invalid. md-cache implements the policy to detect and invoke inode invalidations. fuse-bridge and io-cache implement invalidate handlers to invalidate the respective caches (page cache in the case of fuse).
