[CELEBORN-627][FLINK] Support split partitions
### What changes were proposed in this pull request?
In MapPartiitoin, datas are split into regions.
1. Unlike ReducePartition whose partition split can occur on pushing data
to keep MapPartition data ordering, PartitionSplit only be done on the
time of sending PushDataHandShake or RegionStart messages (As shown in the
following image). That's to say that the partition split only appear at the
beginnig of a region but not inner a region.
> Notice: if the client side think that it's failed to push HandShake or
RegionStart messages. but the worker side can still receive normal
HandShake/RegionStart message. After client revive succss, it don't push any
messages to old partition, so the worker having the old partition will create a
empty file. After committing files, the worker will return empty commitids.
That's to say that empty file will be filterd after committing files and
ReduceTask will not read any empty files.
2. PushData/RegioinFinish don't care the following cases:
- Diskfull
- ExceedPartitionSplitThreshold
- Worker ShuttingDown
so if one of the above three conditions appears, PushData and RegionFinish
cant still do as normal. Workers should consider the ShuttingDown case and try
best to wait all the regions finished before shutting down.
if PushData or RegionFinish failed like network timeout and so on, then
MapTask will failed and start another attempte maptask.
3. how shuffle read supports partition split?
ReduceTask should get split paritions by order and open the stream by
partition epoc orderly
### Why are the changes needed?
PartiitonSplit is not supported by MapPartition from now.
There still a risk that a partition file'size is too large to store the
file on worker disk.
To avoid this risk, this pr introduces partition split in shuffle read and
shuffle write.
### Does this PR introduce _any_ user-facing change?
NO.
### How was this patch tested?
UT and manual TPCDS test
Closes #1550 from FMX/CELEBORN-627.
