(Interactive kubectl) Add a 'Select container' drop-down to the logs drop-down

[lpetkov]

Overview

Per user feedback on Slack:

We are using linkerd in k8s cluster. This injects the sidecar in all our pods and this sidecar becomes the default container. Whenever there is event like creation/crashloopbackoff, the BotKube provides the logs of the default container only. Is there a way where we can configure BotKube to show logs of other containers and not the default one?

Acceptance Criteria

When a user selects the logs option from the Select Actions drop-down, add a secondary drop-down that lists the relevant containers and All option.

Reason

Refer to the user feedback above.
