[FEATURE REQUEST] Support generating password protected PEM private keys

[frankgrimes97]

Could a new param be added to support this?

For context, I tried to use genSelfSignedCert to generate keys for Kafka and was unable to load them because Kafka requires that the private key be password protected.

As it stands, I will need to look at generating them through a different mechanism than Sprig.

FWIW, the error in question is as follows:

org.apache.kafka.common.errors.InvalidConfigurationException: SSL PEM key store is specified, but key password is not specified.
