Is your feature request related to a problem? Please describe.
Using the CLI operator should be able to create config files with bunch of prompts

Right now the eigenlayer operator config create command just creates an operator config file and metadata file with no values.

We want an interactive way where user is asked bunch of questions and based on that, it creates a config with filled fields

Describe the solution you'd like
Operator should be able to create operator config using bunch of prompts

• Do you want to gate stakers approval
  • If yes, then ask for address
  • If not then just fill Zero Address
• Do you want your earning to go to any other address
  • If yes, then ask for new addresss
  • If no, just use the operator address
• What's your eth node?
• ecdsa key path
• bls key path
• network - goerli/mainnet/local?
