func (*IAMSys) SetTempUser 

func (sys *IAMSys) SetTempUser(ctx context.Context, accessKey string, cred auth.Credentials, policyName string) error

SetTempUser - set temporary user credentials, these credentials have an expiry. The permissions for these STS credentials is determined in one of the following ways:

- RoleARN - if a role-arn is specified in the request, the STS credential's policy is the role's policy.

- inherited from parent - this is the case for AssumeRole API, where the parent user is an actual real user with their own (permanent) credentials and policy association.

- inherited from "virtual" parent - this is the case for AssumeRoleWithLDAP where the parent user is the DN of the actual LDAP user. The parent user itself cannot login, but the policy associated with them determines the base policy for the STS credential. The policy mapping can be updated by the administrator.

- from `Subject.CommonName` field from the STS request for AssumeRoleWithCertificate. In this case, the policy for the STS credential has the same name as the value of this field.

- from special JWT claim from STS request for AssumeRoleWithOIDC API (when not using RoleARN). The claim value can be a string or a list and refers to the names of access policies.

For all except the RoleARN case, the implementation is the same - the policy for the STS credential is associated with a parent user. For the AssumeRoleWithCertificate case, the "virtual" parent user is the value of the `Subject.CommonName` field. For the OIDC (without RoleARN) case the "virtual" parent is derived as a concatenation of the `sub` and `iss` fields. The policies applicable to the STS credential are associated with this "virtual" parent.

When a policyName is given to this function, the policy association is created and stored in the IAM store. Thus, it should NOT be given for the role-arn case (because the role-to-policy mapping is separately stored elsewhere), the AssumeRole case (because the parent user is real and their policy is associated via policy-set API) and the AssumeRoleWithLDAP case (because the policy association is made via policy-set API).
