## Which issue does this PR close?
<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases. You can
link an issue to this PR using the GitHub syntax. For example `Closes #123`
indicates that this PR will close issue #123.
-->
- Closes #15126 .
## Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
This provides an important change to the MemoryConsumer API, letting any
memory pool identify which consumer is requesting the memory, and therefor
separate consumers that might have the same name (for example, two
AggregateExec operators in the same Partition)
## What changes are included in this PR?
Nothing except the addition of a unique identifier in the consumer, and an
id() function to retrieve it.
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
Current tests should cover the fact that there is no effect on existing
pools and flows.
In future PRs, I think other memory pools should be converted to reflect
this usage(notably, the TrackedConsumer pool should be able to now correctly
display which consumer has the memory reserved)
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->
<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No breaking changed, just the addition of new user-facing function
