Address conda environment parsing issues

[karthiknadig]

For #10942

• Pull request represents a single change (i.e. not fixing disparate/unrelated things in a single PR).
• Title summarizes what is changing.
• Has a news entry file (remember to thank yourself!).
• Appropriate comments and documentation strings in the code.
• Has sufficient logging.
• Has telemetry for enhancements.
• Unit tests & system/integration tests are added/updated.
• Test plan is updated as appropriate.
• package-lock.json has been regenerated by running npm install (if dependencies have changed).
• The wiki is updated with any design decisions/details.

I looked into this as a part of investigating #10942, since the env list does not have clear separators between name and paths. Since spaces are allowed to in both paths and names, there are some cases where it is not clear ow to extract the name. This is best effort. I wanted to capture the algorithm before I forget.

Another thing in this change is that I removed the stateless helper class.

// Only base environment will have * between name and path.
