Check pod spec for command fields when bridging

[tobifroe]

What is the new feature about?

At the moment, it's impossible to bridge pods that have a command specified in their spec. Gefyra should check whether the pod selected for bridging specifies it's own command. If it does, Gefyra should return an error with a hint instead of swapping the image anyway.

Why would such a feature be important to you?

Gefyra says that bridges are established (which is technically true, I guess?) but the bridged pod crashes unless it can coincidentally execute the command from the pod spec.

Anything else we need to know?
