install streamsync extensions with pip

[FabienArcellier]

A developer can share streamsync extensions as a python package. Components appear in streamsync after a user installs them from pip.

Packages are scanned when the extension starts with streamsync_xxxxxx. The goal is to recognize components added in streamsync from a pip install streamsync_xxxxxxxx.

package demo on pypi: https://pypi.org/project/streamsync_bubblemessage/ package demo/template on github: https://github.com/FabienArcellier/streamsync_bubblemessage

Design

• the python package has to start with streamsync_
• the mecanism is compatible with multi app pattern
• no conflict resolution if 2 pypi package use the same streamsync_ package. I think pip will show an error during installation

Discussions

• design a gallery to promote community components
• transfer of template for distribution from my account FabienArcellier to streamsync-cloud
• the logger usage

I have to move the ExtensionManager into serve module. We want to avoid interaction from core module with the filesystem
