refactor(analysis-platform): move to a separate repo called dm-app-analysis-platform

[KristianKjerstad]

For testing how easy/hard it is to create custom applications.

• [x] Copied over AP code from dmt repo to https://github.com/equinor/dm-app-analysis-platform
• [ ] #3

fixed: waiting for https://github.com/equinor/dm-cli/pull/3

~tried to use the cm-cli and dm-create app to do this. But ran into an issue with cm-cli: it uses the wrong dmss python package version.~
