User Story:
A user currently is not able to create a Disconnected cluster, using IPI, on IBM Cloud.
Currently, support for BYON and Private clusters does exist on IBM Cloud, but support to override IBM Cloud Service endpoints does not exist, which is required to allow for Disconnected support to function (reach IBM Cloud private endpoints).
Description:
IBM dependent components of OCP will need to add support to use a set of endpoint override values in order to reach IBM Cloud Services in Disconnected environments.
The Ingress Operator components will need to be able to allow all API calls to IBM Cloud Services, be directed to these endpoint values, in order to communicate in environments where the Public or default IBM Cloud Service endpoint is not available.
The endpoint overrides are available via the infrastructure/cluster (.status.platformStatus.ibmcloud.serviceEndpoints) resource, which is how a majority of components are consuming cluster specific configurations (Ingress, MAPI, etc.). It will be structured as such

The CCM is currently relying on updates to the openshift-cloud-controller-manager/cloud-conf configmap, in order to override its required IBM Cloud Service endpoints, such as:
data: config: |+ [global] version = 1.1.0 [kubernetes] config-file = "" [provider] accountID = ... clusterID = temp-disconnect-7m6rw cluster-default-provider = g2 region = eu-de g2Credentials = /etc/vpc/ibmcloud_api_key g2ResourceGroupName = temp-disconnect-7m6rw g2VpcName = temp-disconnect-7m6rw-vpc g2workerServiceAccountID = ... g2VpcSubnetNames = temp-disconnect-7m6rw-subnet-compute-eu-de-1,temp-disconnect-7m6rw-subnet-compute-eu-de-2,temp-disconnect-7m6rw-subnet-compute-eu-de-3,temp-disconnect-7m6rw-subnet-control-plane-eu-de-1,temp-disconnect-7m6rw-subnet-control-plane-eu-de-2,temp-disconnect-7m6rw-subnet-control-plane-eu-de-3 iamEndpointOverride = https://private.iam.cloud.ibm.com g2EndpointOverride = https://eu-de.private.iaas.cloud.ibm.com rmEndpointOverride = https://private.resource-controller.cloud.ibm.com
Acceptance Criteria:
Installer validates and injects user provided endpoint overrides into cluster deployment process and the Ingress Operator components use specified endpoints and start up properly.
