Record CloudMapper collect failures and provide them in exceptions

People are running into problems with CloudMapper because they aren't running it with all of the expected privileges. Either due to an SCP or other reason, the `collect` is failing for some of the things it tries to collect. See #536 and #446. This is resulting in confusing issues being filed and likely frustrations for many that ignore the `collect` failures and then don't understand why other commands from CloudMapper aren't working.

I need to have `collect` record something for whether or not it was successful. If it was not successful, I should have later commands throw an error immediately and force the use of a flag like `--bad-idea` or something so they hopefully realize things are going to go poorly for them. Another idea is on any later exceptions, to print information about the collect issues that had been encountered. Another idea is to have a github issue template that asks people if they encountered errors on `collect` when filing their issue.
