[qualys_gav] Fix rate limit headers missing error

[brijesh-elastic]

Proposed commit message

qualys_gav: fix rate limit headers missing error

This removes the rate limit calculations for the `/auth` API call, because we don't receive
the necessary headers from it. It is also mentioned in the [documentation](1) that
rate limits do not apply to the "auth" API (JWT Token Generation API).

Note

After resolving the rate limit missing rate error, I was unable to collect all events from qualys_gav. It only ingested events for 2 intervals. After investigation, it appears that rate was set too low or more throttled than what the server's rate limit headers indicate. (See issue.)
