Add additional error handling in code which creates deployments

[jtaleric]

Proposal / RFE

@christarazi brought up a good point in my PR(#708 ), which makes me think we should add additional error handling when working with the k8s-api.

See the suggestion here : https://github.com/cilium/cilium-cli/pull/708#discussion_r816348864

Is your feature request related to a problem?

Could result in flaky results when talking to the k8s api.
