Rsync nocheck

[lskatz]

What type of PR is this?

• Bug fix

Describe the change

Rsync checks for a remote pid file and it usually is too conservative. I am removing this check.

Does it change the usage of SneakerNetPlugins.pl?

No

Did you add any unit testing? Please describe

Additionally, I am adding in better unit testing using conda.

• Switched most software installation to conda
• Added caching of conda installations
• Removed Kraken testing because the smallest I could make the database was 8G which is too big for the Github environment.
