Add additional prod RHSSO issuer to fix auth issues on integration

[kovayur]

Description

Fleet Manager doesn't trust JWT tokens issued by prod RHSSO if it is pointed to RHSSO stage (#2467). This change makes FM trust tokens issued by both issuers regardless of the base RHSSO url setting.
This PR also disables the additional issuers on the stage environment to make it closer to production.
