Description

At the moment, Flink has several timeout options:

• akka.ask.timeout: Timeout for intra cluster RPCs (JM <-> RM <-> TE)
• web.timeout: Timeout for RPCs between REST handlers and RM, JM, TE

At the moment, these values are separately configured. This requires the user to know about both configuration options and that Flink has multiple timeout values.

In order to simplify setups I would suggest that web.timeout defaults to akka.ask.timeout, if web.timeout has not been explicitly configured. This has the benefits that the user only need to know about a single timeout value which is applied cluster wide.
