We are creating a user-assigned identity in the installer SDK. Testing shows that this identity is unnecessary (and we have a customer case where they would like to backport this). Removing the creation of this identity will simplify the configuration we need to maintain for the Azure & Azure stack install paths.

Acceptance Criteria:

Description of criteria:

• No longer creating the identity, clusters still install successfully

Engineering Details:

• Originally these identities were used to authenticate the kubelet but now that is handled by credentials requests
• https://github.com/openshift/installer/blob/main/pkg/infrastructure/azure/azure.go#L147
• When that is removed, the machine manifests would also need to be updated to not expect the user assigned identity

This requires/does not require a design proposal.
This requires/does not require a feature gate.
