        Updates a Cloud Security Command Center (SCC)
        RemediationIntent resource.\n
        Fields specified in update-mask flag are updated. Updatable fields depends on the state transition.\n
        Valid state transitions are:\n
        a) ENQUEUED to IN_PROGRESS (mask: state,remediation_input)\n
        b) REMEDIATION_SUCCESS to PR_GENERATION_SUCCESS (mask: state,remediation_artifacts)\n
