Cleanup clusterloader2 load testing experimental config file

[maniSbindra]

As a part of #1125, default value of the variables
ENABLE_CONFIGMAPS, ENABLE_DAEMONSETS, ENABLE_JOBS, ENABLE_SECRETS, and ENABLE_STATEFULSETS are set to true, and these values are not overriden in any of the tests. The clusterloader2 load testing experimental-config.yaml file can now be be simplified as discussed in #1036 (comment)

Hi @maniSbindra. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Hmm - apparently I was wrong and this config is used (even though it wasn't modified for the last 7 months or so).
@mm4tt - what is it used for now comparing the the regular load test?

[wojtek-t]

Ohh I see now - it's merging load and density...

@maniSbindra - sorry for that; apparently this is still used, so if you could actually revert this change and migrate actually clean up the unused vars the same way you did for other tests, it would be great!

[maniSbindra]

Thanks will make the required changes.
