Teleport on ephemeral MCs

[gawertm]

Question

• How can we have teleport access for ephemeral MCs (clusters are used for CI tests)

• [x] Kubernetes access

• [x] SSH access

Problem

• Since, ephemeral MCs is re-created frequently, the JWKS key changes often which we require for teleport-operator.
• Alternatively, we can use static credentials for ephemeral MCs but that would require some changes to teleport-operator.
