Capture create doesn't detect CLI version

[kamilprz]

Description of Issue

Capture create does not pick up image version accurately.

See there is no version number after "retina-agent" -

This leads to the pods failing to be created as they try to pull an image without a version -

To Reproduce

Run kubectl retina capture create -n default.

Check kubectl get pods - you will see Status - InvalidImageName

Goal

Fix the way that the version is pulled and define a default if one is not present.

Definition of Done

retina capture create can run successfully, creating the jobs and pods without failure.

Trying to understand whether the issue persists - or whether it is a configuration issue on my end.

When installed with Krew, it works as expected.
