Describe the solution you'd like

There are use-cases where a secret could be generated by the operator instead of using pre-existing ones from the secret store. For example a MongoDB could be spun up using a password generated by the operator. This password is then used by an application in the cluster to access the database. No human ever needs to read that secret or have to specify it beforehand. A similar feature is available in a project called VaultOperator which tries to solve similar problems like this operator just for Hashicorp Vault as a secret store.

What is the added value?

Secrets can be generated automatically without manual interaction with the secret store.

Give us examples of the outcome

Example of generators:

• string generates a random string where length and character set can be specified.
• bytes generates random bytes with a given length
