Description of problem:
From Azure documentation[1], some words are preserved and could not be used as a resource name.
Tested to set metadata.name in install-config with various preserved words mentioned in doc[1], following preserved words could not be set as metadata.name as a whole word or substring.
1) The following words can't be used as either a whole word or a substring in the name:
MICROSOFT
WINDOWS
2) The following word can't be used at the start of a resource name, but can be used later in the name:
LOGIN
Otherwise, installation failed with below error when creating user-assigned identity:
