Instascale Epic

These are some focus issues for instascale, bringing them together as I feel there are higher priority:

Issues

• [x] https://github.com/project-codeflare/instascale/issues/80
• [x] https://github.com/project-codeflare/instascale/issues/143
• [ ] https://github.com/project-codeflare/instascale/issues/172
• [ ] https://github.com/project-codeflare/instascale/issues/163
• [ ] https://github.com/project-codeflare/instascale/issues/173
• [ ] https://github.com/project-codeflare/instascale/issues/44
• [ ] https://github.com/project-codeflare/instascale/issues/73
• [x] https://github.com/project-codeflare/instascale/issues/175

I also believe after these changes, a refactor of instascale may be on the table, to reduce the duplication between machine types, and allow for further extension.

I'm open to any discussions about adding/removing priority issues if there are any suggestions also :)
