    [FLINK-7384][cep] Unify event and processing time handling in the Abs…

    *Thank you very much for contributing to Apache Flink - we are happy that 
you want to help us improve Flink. To help the community review your 
contribution in the best possible way, please go through the checklist below, 
which will get the contribution into a shape in which it can be best reviewed.*
    *Please understand that we do not do this to make contributions to Flink a 
hassle. In order to uphold a high standard of quality for code contributions, 
while at the same time managing a large number of contributions, we need 
contributors to prepare the contributions well, and give reviewers enough 
contextual information for the review. Please also understand that 
contributions that do not follow this guide will take longer to review and thus 
typically be picked up with lower priority by the community.*
    ## Contribution Checklist
      - Make sure that the pull request corresponds to a [JIRA 
issue]( Exceptions are 
made for typos in JavaDoc or documentation files, which need no JIRA issue.
      - Name the pull request in the form "[FLINK-1234] [component] Title of 
the pull request", where *FLINK-1234* should be replaced by the actual issue 
number. Skip *component* if you are unsure about which is the best component.
      Typo fixes that have no associated JIRA issue should be named following 
this pattern: `[hotfix] [docs] Fix typo in event time introduction` or 
`[hotfix] [javadocs] Expand JavaDoc for PuncuatedWatermarkGenerator`.
      - Fill out the template below to describe the changes contributed by the 
pull request. That will give reviewers the context they need to do the review.
      - Make sure that the change passes the automated tests, i.e., `mvn clean 
verify` passes. You can set up Travis CI to do that following [this 
      - Each pull request should address only one issue, not mix up code from 
multiple issues.
      - Each commit in the pull request has a meaningful commit message 
(including the JIRA id)
      - Once all items of the checklist are addressed, remove the above text 
and this checklist, leaving only the filled out template below.
    **(The sections below can be removed for hotfixes of typos)**
    ## What is the purpose of the change
    *(For example: This pull request makes task deployment go through the blob 
server, rather than through RPC. That way we avoid re-transferring them on each 
deployment (during recovery).)*
    ## Brief change log
    *(for example:)*
      - *The TaskInfo is stored in the blob store on job creation time as a 
persistent artifact*
      - *Deployments RPC transmits only the blob storage reference*
      - *TaskManagers retrieve the TaskInfo from the blob cache*
    ## Verifying this change
    *(Please pick either of the following options)*
    This change is a trivial rework / code cleanup without any test coverage.
    This change is already covered by existing tests, such as *(please describe 
    This change added tests and can be verified as follows:
      - *Added integration tests for end-to-end deployment with large payloads 
      - *Extended integration test for recovery after master (JobManager) 
      - *Added test that validates that TaskInfo is transferred only once 
across recoveries*
      - *Manually verified the change by running a 4 node cluser with 2 
JobManagers and 4 TaskManagers, a stateful streaming program, and killing one 
JobManager and two TaskManagers during the execution, verifying that recovery 
happens correctly.*
