Expose API for when the list of interpreters have changed #17004
Description
Discussed in #16683

Currently there's no way for Jupyter to know when user creates a new Python environment (conda, or the like).
Is it possible to get an event so we know that new interpreters have been created.
Note: Once thats done, how would we get these new interpreters. Not sure the GetInterrpeters is the best API for this, as that will return all interpreters all over again. Personally it would be nice to have something we can subscribe to, like an observable, this way we only get whats new).

Yup, that was my original plan for how the interpreters could be exposed.
#3023
Having an observable is a very efficient way for Jupyter as well. E.g. we don't need to wait till we get all interpreters just to know that the user has
an interpreter, similarly when we search for kernels we don't need to wait for all when we can start searching incrementally. (these were some of the perf improvements we discussed when looking at the delays in Jupyter extension)brettcannon commentedon Sep 1, 2021

This is now available via the proposed API for the python extension, please try this out and let us know.
Event for when the interpreter list changes:
vscode-python/src/client/apiTypes.ts
Line 172 in 65c22e4
API to get currently know interpreters:
vscode-python/src/client/apiTypes.ts
Line 145 in 65c22e4
API to get details for a given interpreter path:
vscode-python/src/client/apiTypes.ts
Line 135 in 65c22e4
API to get the refresh promise, this will return a promise for the current ongoing discovery:
vscode-python/src/client/apiTypes.ts
Line 167 in 65c22e4
API to trigger refresh of environments:
vscode-python/src/client/apiTypes.ts
Line 162 in 65c22e4

I believe the API supports notification of when the interpreter list has changed, so closing as done.
