Jesse strategy break point debugging in vscode.

[qwpto]

As a developer I'd be nowhere without breakpoint debugging, and I wanted to bring the other people I'm collaborating with up to speed on developing software so they needed this capability to learn how to write python. I'm using vscode to develop with Jesse. So I've forked the project-template and updated it to work automatically with vscode which means it will provide the user prompts to install docker, open in a container, etc. It also gives them a single button press to start debugging the code. It will work for both docker (in linux and windows) and with the jesse app natively in windows and linux.

Note: https://code.visualstudio.com/docs/containers/docker-compose
"In Python projects, you have the Dockerfile, .dockerignore, docker-compose*.yml files all in the root folder of the workspace. When you add another app or service, move the Dockerfile into the app's folder."

The workflow is:

• (OPTIONAL) follow the desired setup instructions for your jesse environment (you can skip this if you just want to use docker as vscode will prompt you through all the setup)
• install vscode
• Create a new strategy project from this template
• open this new project in vscode as a folder
• vscode will then prompt you through the remaining steps (eg opening the project in the dev-container, installing python, etc)

Once you're ready to debug a strategy:

• open the file of the strategy in vscode
• insert a break point by clicking in the left margin (near the line numbers)
• navigate to the debugging tab as shown in the image (1)
• choose your debugging environment as shown in the image (2) eg jesse docker debug
• then just click play to start debugging as showing in the image (3)

you can inspect the program flow, variable values, and start experimenting with your strategy in the debug console against the candle data. oh and poke around at the internals of jesse if that's what you're into.

Worth noting for this one, it's really useful to edit the break point for a specific candle you're debugging eg:
datetime.utcfromtimestamp(self.time/1000).strftime('%Y-%m-%d %H:%M:%S') == '2021-07-20 02:47:00'
