chrislu 6c7fe40305 filer sink retries reading file chunks, skipping missing chunks 
if the file chunk is not available during replication time, the file is skipped

chrislu b463ca1a2f filer replication: compare content changes directly 
Fix https://github.com/seaweedfs/seaweedfs/issues/3714

The destination chunks may be empty. For example, the file is updated and the volume is vacuumed. In this case, the sync would miss the old chunks. This is fine. However, the entry would have correct metadata but missing chunks.

For this case, the simple metadata comparison would be wrongly skipping data changes, and the file will stay empty unless file content md5 is changed.

chrislu 9405eaefdb filer.sync: fix replicating partially updated file 
Run two servers with volumes and fillers:
server -dir=Server1alpha -master.port=11000 -filer -filer.port=11001 -volume.port=11002
server -dir=Server1sigma -master.port=11006 -filer -filer.port=11007 -volume.port=11008

Run Active-Passive filler.sync:
filer.sync -a localhost:11007 -b localhost:11001 -isActivePassive

Upload file to 11007 port:
curl -F file=@/Desktop/9.xml "http://localhost:11007/testFacebook/"

If we request a file on two servers now, everything will be correct, even if we add data to the file and upload it again:
curl "http://localhost:11007/testFacebook/9.xml"
EQUALS
curl "http://localhost:11001/testFacebook/9.xml"

However, if we change the already existing data in the file (for example, we change the first line in the file, reducing its length), then this file on the second server will not be valid and will not be equivalent to the first file

This problem occurs on line 202 in the filer_sink.go file. In particular, this is due to incorrect mapping of chunk names in the DoMinusChunks function. The names of deletedChunks do not match the chunks of existingEntry.Chunks, since the first chunks come from another server and have a different addressing (name) compared to the addressing on the server where the file is being overwritten.

Deleted chunks are not actually deleted on the server to which the file is replicated.

chrislu 9f9ef1340c use streaming mode for long poll grpc calls 
streaming mode would create separate grpc connections for each call.
this is to ensure the long poll connections are properly closed.
