Create a new command to generate reports based on RBAC

[camilamacedo86]

Create a new command for the audit tool that can generate reports which will return all Operators of some index that has some specific RBAC set on the CSV. This new command would work similar to audit custom validator [OPTIONS] --filter-validation="" that returns a list of Operators which containers that validation.

See the code for the validator command as an example:
https://github.com/operator-framework/audit/tree/main/cmd/custom/validator

See the code for a specific need script report that looks for a specific RBAC:
https://github.com/operator-framework/audit/tree/main/hack/specific-needs/rbacmachine

The goal of this command is to generate the same report done with https://github.com/operator-framework/audit/tree/main/hack/specific-needs/rbacmachine but instead of we have the data fixed on the code we would be able to inform it from flags.
