Add support for Argo Rollout workloads

[maxlegault]

Please describe your use case / problem.
Currently, workloads that can be intercepted are Deployments, ReplicaSets and StatefulSets. It would be great to also support Argo Rollouts for users that use these workload types to leverage rollout strategies like blue/green and canary.

As of now, for a service foo that points to Rollout controlled pods, the following error is printed:

> telepresence intercept foo
telepresence: error: No interceptable deployment, replicaset, or statefulset matching foo found

Describe the solution you'd like
Support adding the traffic-agent configuration to a Rollout object. Its specs are mainly the same as a Deployment with some additional properties.

Describe alternatives you've considered
It is currently possible to intercept the ReplicaSet associated to a Rollout object like this (foo-57bc7c4959 being a ReplicaSet created by the Rollout controller):

> telepresence intercept foo --workload foo-57bc7c4959

This will work for a first time intercept, but as soon as the Rollout object gets updated, the updated ReplicaSet will be scaled down to 0 and a new one will be scaled up, replacing the traffic-agent-enabled pods.

Versions (please complete the following information)
Telepresence 2.5.0
Kubernetes 1.20
