[jira] [Updated] (FLINK-7378) Create a fix size (non rebalancing) buffer pool type for the floating buffers

zhijiang updated FLINK-7378:
Description:
Currently the number of network buffers in {{LocalBufferPool}} for
{{SingleInputGate}} is limited by {{a * + b}}, where a is
the number of exclusive buffers for each channel and b is the number of
floating buffers shared by all channels.
Considering the credit-based flow control feature, we want to create a fix size
buffer pool used to manage the floating buffers for {{SingleInputGate}}. And
the exclusive buffers are assigned to {{InputChannel}} s directly.

Considering the credit-based flow control feature, we want to implement a new

{{SingleInputGate}}.
Compared with {{LocalBufferPool}}, this is a non-rebalancing buffer pool which
will not participate in redistributing the left available buffers in
{{NetworkBufferPool}}.
