Ship should always store a debug log

[dexhorthy]

Expected behavior

When ship exits with an error, it should leave a ship-debug.log file in .ship, which can be included in support inquiries.

Actual behavior

When ship fails due to an error, the user is instructed to re-run ship with --log-level debug, and use that output for support inquiries.

Information

• Ship version: 4931a46
• Docker version: n/a
• Command line run: ship init github.com/helm/charts/stable/nginxxxxx

Steps to reproduce the behavior

1. Run ship init above
2. see it fail
3. re-run with --log-level=debug is required to get useful debugging logs.

@marccampbell assigning to you to review, feel free to remove yourself and the needs/review label if you're 👍 on this

[marccampbell]

@dexhorthy is the proposal then to create a debug.log at start, and defer deletion of that file until the application exits successfully? This would cause a successful execution to not leave the file, but a failed one to leave it?

[dexhorthy]

@marccampbell something like that, I haven't 100% settled on the implementation, but my feeling is only to leave that file if there was an issue

@dexhorthy 👍 from me on this.
