[GitHub] trafficserver pull request #1521: Changes default RAM cache to the LRU + see...

Changes default RAM cache to the LRU + seen-filter

It turns out, the CLFUS is either having a bug/issue, or doesn't work well
with some content. But several of our users have reported noticeable (2-3x)
better cache hit ratio with the LRU vs the CLFUS. The issues with the
CLFUS cache happens over time in at least my tests, where it can take up to
24h for it to deteriorate noticeably. This is likely why it has gone 
unnoticed
for so long.

This should also be backported into 7.1.x.
