PTVS Profiling Revamp

[AdamYoblick]

We've been asked to refactor our python profiling code to mesh with the new profiling system that VS built.

This work is spread between PTVS (me), a python extension (Steve Dower), and the VS team.

Work remaining for me:

• [ ] Pull in Steve's profiling package, ask him to put it somewhere upstream of the msft_consumption feed so we can ingest it as part of our build.
  • Package is at https://dev.azure.com/mseng/Python/_artifacts/feed/Python@Prerelease/PyPI/etwtrace/overview/0.1b3.
  • It will need to be moved to a public feed, then added to an upstream of the msft_consumption feed at https://dev.azure.com/azure-public/vside/_artifacts/feed/msft_consumption. OR just add it to PyPi.
• [ ] Make sure the package gets bundled up into one of the existing VSIX files generated through our CI build
  • This needs to be a "fat" install, taking in files from all the wheels, since we don't know what platform/python version the user will have, so we package all of them. See install_debugpy.py for an example of how to do this.
  • [x] Manually download the etwtrace package and use install_wheels.py to install and merge the wheels into the packages folder.
  • [x] Modify the build scripts to grab this new folder and include the files in one of the vsix files.
• [ ] Once the package makes it into VS, make sure we install it and/or invoke it when profiling
• [ ] Do the work to show up in the Performance Profiler UI (see below):

Notes from the VS team:

Here is some info on how to show up in the Performance Profiler (Alt+F2) UI. Grab our SDK package (Package Details - Azure Artifacts (visualstudio.com)) then export an ITargetProvider.

ITargetProvider: Anything that implements this interface shows up in that “select target” dropdown.

• ProcessTargetProvider.cs - Repos (visualstudio.com)  This is the one for our attach to process selection
• DockerTargetProvider.cs - Repos (visualstudio.com)
• RunningWindowsStoreAppTargetProvider.cs - Repos (visualstudio.com)
• WindowsStoreAppTargetProvider.cs - Repos (visualstudio.com)

The main method where the action happens is GetTargetsAsync which returns the ITarget that the profiler uses.
