Reload improvements: Add retry to shell copy and --no-build to a part

[michaellee1019]

Two improvements to the reload process:

• Adds an automatic retry to the shell copy. I've seen various scenarios where shell service can fail and I think we should be defensive in the reload process for it. Due to networking situations or user error, subsequent copies to the part can pass once the part is online.

• Allows for copying an existing build artifact that you have locally to the same part again or another part using --no-build. Before this change --no-build was used only for reload-local to do the same thing. I reorganized the folders to omit the part-id from the file path and we now persist the latest binary for each platform in the same folder. I feel like its more organized this way.

Testing:

Retry is displayed to the user and correctly connects and copies the file after a few failures. To simulate this I restarted the part while the copy was happening.
