[FLINK-5867] [FLINK-5866] [flip-1] Implement FailoverStrategy for pipelined
regions
This is based on #3772 , the relevant commits are the latter four.
The majority of the work has been done by @tiemsn , with some rebasing and
additions from me.
# Pipelined Region Failover
As described in
[FLIP-1](https://cwiki.apache.org/confluence/display/FLINK/FLIP-1+%3A+Fine+Grained+Recovery+from+Task+Failures),
this pull request implements the detection of pipelined regions in the
`ExecutionGraph` and failover within these pipelined regions.

[FLINK-5869] [flip-1] Add basic abstraction for Failover Strategies to
ExecutionGraph
- Rename 'ExecutionGraph.fail()' to 'ExecutionGraph.failGlobally()' to
differentiate from fine grained failures/recovery
- Add base class for FailoverStrategy
- Add default implementation (restart all tasks)
- Add logic to load the failover strategy from the configuration
