Zombienet generates the keys and puts them into the expected path here:

I am using zombienet to test a node that has a different keystore path, so currently what I do is to manually copy the keystore files to the path I expect. But it would be really nice if zombienet allowed me to override the default path.

My use case:

// path used by zombienet:
/tmp/zombie-asdf/Collator1000-01/data/chains/simple_container_2000/keystore
// the custom path I want:
/tmp/zombie-asdf/Collator1000-01/relay-data/chains/dancelight_local_testnet/keystore

Describe the solution you'd like

Add an optional field under "parachains.collators", customKeystorePath.

I need the path to depend on the node dir, so maybe we need something similar to #2077

I can implement it if you tell me whats the easiest way to do it.
