HttpRecorder optimization for large recorded files

[shahabhijeet]

• LRO retries makes the recorded file size bigger, that results in failing to open on CI machine when CI machines are running low on resources.
• Adding feature to http recorder to compress LRO recorded files. This will eliminate LRO retries during playback.
• The current iteration of optimization resulted in eliminating ~40% LRO payload out of recorded files.
• During compacting of the files, it creates a backup of original file incase the test author decides to have both recordings (uncompressed as well as compressed)
• Added additional key-vaule pair to trigger compressing recorded file in testFx. The new Key-Value pair is OptimizeRecordedFiles=true/false
• Added unit tests. Recorded full E2E tests and compressed the recorded file.
• Refactored test project to minimize redundant files, refactored namespaces in test projects.
• Rearranged project files to comply building with multiple target frameworks.
• Added additional meta data that will allow to query recorded data on multiple pivots (operation type, header type etc.)
