Conditionally added AWS_STS_REGIONAL_ENDPOINTS flag

[holmesb]

to controller's efs-plugin container. Is needed to create persistent volumes on private EKS clusters. Without this, dynamic pv creation errors: "Failed to fetch File System info: Describe File System failed"

Is this a bug fix or adding new feature?
new feature (adds support for private eks clusters)

Hi @holmesb. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.

Is anyone able to review this? Probably fixes issues #555 & #499
