<!--
*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.
**(The sections below can be removed for hotfixes of typos)**

## What is the purpose of the change
*This is the final step towards unification between SQL parser and SQL
Client parser. In this PR,*
- *Remove the SQL Client parser and use the parser from the TableEnvironment
to parse `Operation`.*
- *Remove `ResultStore` and let the CliView to close the `TableResult` by
themselves.*
The reason why we decide to remove `ResultStore` as follows:
- *The `CliView` has the ability to capture the cancel from the user side
and don't need to rely on the `Executor` to stop the job*
- *After remove the `ResultStore`, the `Executor` is just a manager of the
`SessionContext` and doesn't need to care about the cancel of the query.
Therefore, we can merge the `executeSql` and `executeQuery` into one.*
## Brief change log
- *Remove the useless SqlClient parser and `ResultStore`*
- *Replace `executeSql` and `executeQuery` with `executeOperation` in the
`Executor`*
- *Replace `getParser` with `parseStatement` in the `Executor`*
