[FLINK-13019][coordination][tests] IT test for fine-grained recovery

[azagrebin]

What is the purpose of the change

The simplest IT test is to create a batch job with a sequence of non-parallel mappers.
The each mapper writes to a blocking partition which means the next mapper starts when the previous is done.
The mappers are not chained into one Task which makes them separate failover regions.
