remove the need of ecdsa key by default

[shrimalmadhur]

• This PR removes the need of ECDSA key while running the node by default. Operator can still choose to use but there will be extra steps required and would generally be not recommended

This PR also changes interfaces for all operations.

Note: Same .env file is being used for these operations and running node. Even though only few variables are needed from the .env files for run.sh script, to have minimal change I want to keep .env for this too. But this is debatable if we want to remove .env file for run.sh we have to make everything as argument and also need to make sure nodeplugin doesn't require any unnecessary fields from .env file

Do we still generate this key in EigenLayer cli by default?

[shrimalmadhur]

by default we don't generate any key - they can generate or not but - it's not them.
