*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](https://issues.apache.org/jira/projects/FLINK/issues). Exceptions are
made for typos in JavaDoc or documentation files, which need no JIRA issue.
- Name the pull request in the form "[FLINK-XXXX] [component] Title of the
pull request", where *FLINK-XXXX* 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 Azure Pipelines CI to do that following [this
guide](https://cwiki.apache.org/confluence/display/FLINK/Azure+Pipelines#AzurePipelines-Tutorial:SettingupAzurePipelinesforaforkoftheFlinkrepository).
- 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.

## 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).)*
For supporting customized k8s scheduler, we need to extend the ability of
current code tree to support the cases of all customized k8s scheduler during
they schedule the real pods. So we'd better to extend all cases during k8s
scheduling, such as before/during/after our target resources creation. In this
PR, we add the `before` case. And current code tree had covered during/after
cases.
## Brief change log
1. We introduce a new interface func for all decorators to support
create pre-prepared k8s resources.
2. We extend a attribute for JM spec for storing the resources list.
3. Extending the ability for supporting refresh the preprepared
resource's ownerreference based on original code logic.
4. Add the ability for creating K8S resource before JM deployment
creation in Fabric client.
## Verifying this change
We can not verify this change at this moment, as this is a internal process
in flink-kubernetes now. It doesn't affect the user interface now. The only way
we can test it is mocking a JM spec with another k8s resources which is not
contained by Flink. And check whether the resources can be created before the
JM and refresh the correct ower reference(Flink cluster id-- deployment id).
## Does this pull request potentially affect one of the following parts:
