Looking pretty good so far! I left some comments in-line, nothing super-major though. It's mostly about some potential extraneous configuration and missing tests.

Looks good!! Just one more comment about /metrics path for gateways, but I won't block on that, assuming it's addressed.

I think we need to hard-code this one to /metrics (that's how it worked before). This value is controlled by the value from the connectInject stanza which usually does not control gateways. Also, if someone changes this value, the prometheus annotations on the gateway deployment will not change because we're not consuming this value in the gateway annotations.
