## Description
QTIP (QUIC over TCP): A variant of QUIC with TCP headers instead of UDP headers. This is different from a TCP tunnel in that it does not use TCP’s retransmission and congestion control logic: it simply uses TCP headers (and a few pure TCP SYN and RST packets with no QUIC payload) to masquerade as TCP traffic.
Client Side:
1. When the initial packet is passed down to raw datapath, we cache the send and send a SYN instead.
2. When SYN+ACK is received, we send an ACK and then resume the initial packet and construct a RST to be sent later (because at this moment we know what sequence and ACK numbers to use).
3. When the first data packet is received, we will know what sequence number and ACK number to use. The ACK number after handshake is always acking the peer's SYN+ACK. The sequence number is always ISN+2, where ISN+1 is reserved for RST. By doing so, all data packets are retransmissions but still in window.
4. When the QUIC connection is shut down, the cached RST is sent.
Server side:
1. Statelessly respond to all SYN/FIN received.
2. When the first data packet is received, it's identical to 3.
* Test perf log grabbing
* Fix
* Try more logging
* Try to see if stopping logs is failing
* Remove copies
* 1 more fix
* Move log stop to its own task
* Add way to force iterations
* Add way to cancel logs
* Remove some unnecessary changes
* Enhance performance logging capabilities
Use the existing log scripts to perform logging, allow perf pipeline to log any supported log profile
* Fixup log profile
* Fix script root
* Fix cleanup
* A bit more logging, mainly to figure out why robocopy failed. And fix local
* Fix remote
* Another client and server fix
* Fix runs
* Disable prints
* Extra new line..
* 1 more log fix
* Remove stub TLS
We were only using stub TLS to be compatible with ASAN. Now that OpenSSL and Asan work together, we can remove stub TLS and reduce our TLS scope.
* Fail build if throughput up test has a 5% or more performance drop
* Allow tests to finish, write failures at end
* Move thesholds to json files
* Fail loopback on regressions to, but use larger threshold
* Fix arguments
* Actual print failures at end
* Fix all negative regressions not counting
* Print more
* Slightly different output
* Fix not triggering

* Combine loopback and remote into a single script.
By doing this, we make things much easier for PGO
* Fix perf pipeline
* Fix tools lookup
* Update PGO
New performance driver is custom built specifically for performance, rather then using quicping.
Also will be compatible with server mode, and baseline support is part of this commit.
Perf Tests can now run either locally or cross systems. A setup has been created to make this work automatically on AZP.
Additionally, machine name is now published, along with other smaller code changes.
