Operator config should support key name

[shrimalmadhur]

Is your feature request related to a problem? Please describe. Currently operator-config.yaml requires full path to private keys. Given that we create keys with name we should be able to use just the key name while doing operator registration.

Describe the solution you'd like Replace path with keyname and add logic to handle that in all the places

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
