[FLINK-4545] replace the network buffers parameter
(based on #3708 and #3713)
Instead, allow the configuration with the following three new (more
flexible) parameters:
* `taskmanager.network.memory.fraction`: fraction of JVM memory to use for
network buffers (default: 0.1)
* `taskmanager.network.memory.min`: minimum memory size for network buffers
(default: 64 MB)
* `taskmanager.network.memory.max`: maximum memory size for network buffers
(default: 1 GB)
Note that I needed to adapt two unit tests which would have been killed on
Travis CI because these defaults result in ~150MB memory being used for network
buffers which apparently was too much there.

[FLINK-4545] update the docs with the changed network buffer parameter
Also update the descriptions of taskmanager.memory.fraction not being
relative
to the full size of taskmanager.heap.mb but that network buffer memory is
subtracted before!

[FLINK-4545] fix some tests being killed on Travis CI
Due to the increased defaults for network buffer memory use, some builds on
Travis CI fail with unit tests being killed. This affects
* RocksDbBackendEventTimeWindowCheckpointingITCase and
* HBaseConnectorITCase
We fix this by limiting the maximum amount of network buffer memory to 80MB
(current defaults would yield 150MB, previously 64MB were used).
