APIML login fails due to timing

[struga0258]

We have noticed during some api test that we keep getting login failures due to the APIML. We believe its a timing issue but its happening frequently. We keep getting the following errors:
"ZWEAG121E - Authorization header is missing, or the request body is missing or invalid for URL '/gateway/api/v1/auth/login'"
"Authentication credentials not found"

Steps to Reproduce

To reproduce this issue we have created a python script that just loops and sends a post request to the following url path '/gateway/api/v1/auth/login'. We noticed that if you increase the wait before the request this issue goes away so it seems to be a timing issue.

@struga0258 What version of z/OSMF and API Mediation Layer is being used in this test?

We used both latest v2 and v3 Zowe to test this, I believe the z/OSMF version is 29.0
