[FLINK-5129] make the BlobServer use a distributed file system
Make the BlobCache use the BlobServer's distributed file system in HA mode: previously even in HA mode and if the cache has access to the file system, it would download BLOBs from one central BlobServer. By using the distributed file system beneath we may leverage its scalability and remove a single point of (performance) failure. If the distributed file system is not accessible at the blob
caches, the old behaviour is used.
@uce can you have a look?

[hotfix] remove unused package-private BlobUtils#copyFromRecoveryPath
This was actually the same implementation as
FileSystemBlobStore#get(java.lang.String, java.io.File) and either of the two
could have been removed but the implementation makes most sense at the
concrete file system abstraction layer, i.e. in FileSystemBlobStore.

[hotfix] simplify code in BlobCache#deleteGlobal()
Also, re-order the code so that a local delete is always tried before creating
a connection to the BlobServer. If that fails, the local file is deleted at
least.

[FLINK-5129] make the BlobCache also use a distributed file system in HA mode
If available (in HA mode), download the jar files from the distributed file
system directly instead of querying the BlobServer. This way the load is more
distributed among the nodes of the file system (depending on its implementation
of course) compared to putting all the burden on a single BlobServer.
