feat: checks if operator exists for server-related cmds

[bartoszmajsak]

Short description of what this resolves:

The check is performed by simply ensuring that CRD exists and failing with hint installation otherwise. For now it's only applied to ike develop as that's the only command interacting with the cluster on the client side. Others, such as create or delete can be e.g. run as part of Tekton task.

Changes proposed in this pull request:

• root command incorporates check for installation prereq for all commands which require server/cluster side interaction
• commands should be marked with special annotation in order for this check to be performed

Annotations: map[string]string{
			cmd.AnnotationOperatorRequired: "true",
		},

• reworks pre-runs to fulfil this req
• adds dynamic client which is used for the check

Fixes #1023
