VCL: rate limit text-frontend requests
 
Analytics data indicates that 300/60s should cover the full request load
for the worst single client IP we can see in the past week (an MSFT IP,
likely a Bing crawler). Moreover, our ratelimiting here only applies to
cache miss/pass traffic, not cache hits, further adding lots of headroom
for normal cases.

To err on the side of caution, exempt seemingly-authenticated requests.
