Dashboard - Ability to set test logo

[mogopz]

Is your feature request related to a problem? Please describe. All of our tests are using custom executors which are based on the official Testkube executors but they have affinity/resources set. Since we're using custom executors we lose the logos on each of our tests. When looking through a dashboard with a handful of tests the logos can be useful to quickly figure out what type of test you're looking at.

Describe the solution you'd like The ability for a custom executor to inherit an existing logo.

Describe alternatives you've considered We're currently using labels which works fine, but logos are even better!

Was thinking some time ago to allow set link to image in Executor CRD.
