Use tide for PR merging

[spiffxp]

This is a core repository. As such, it needs to use the same merge automation as the rest of the project

I have a PR open that will address this at an org-wide level: kubernetes/test-infra#9342. It will:

• enable the approve plugin, to allow use of the /approve plugin
• enable the blunderbuss plugin, to assign reviews based on OWNERS files
• add all repos in the kubernetes org to tide's query

Can one of the repo maintainers here drop an LGTM (or objections) on the linked PR? Alternatively, if I hear no objections by Monday 10am PT of next week, I will merge the PR.

Thanks a lot @spiffxp for helping enable this, it's awesome!

Just LGTM on the linked PR.
