Conda build should have several stages to be called independently

[oleg-alexandrov]

Summary

The conda-build toolset is nice and save work, but can be a pain to use because it is very slow. Then, if it fails, one has to restart everything, wait for a long time, and then likely fail again, and having to restart.

It should have the ability to resume a failed build, and also to resume at packaging, if that step failed. This would really save a lot of work.

The epic label and issue is used to group tickets together by the conda-core devs, so removing for now.

To add, it would be nice if this tool would have stages, such as:

conda-build --resume-build (resume latest build where it used to fail before, do not get dependencies)

conda-build --package (start at packaging, so after build/install)

This way the programmer can try to fix things then let conda-build take over.

Hoping this is looked into. Conda is so awfully slow, and debug cycles take a very long time. Conda should have a way of using a given environment without having to solve dependencies each time, and it should be able to resume where it failed.
