The examples test output is not good

[Leo Arias]

The results of successful and failed examples tests is not good. It's hard to parse, and doesn't provide all the information needed to understand the steps that lead to an error.

Some things we can do to improve it:

Print the commands executed and their output as they are run.
Print a summary at the end of the execution.
Replace the \n and \t in the output detail with proper white spaces.

[Impact]

 * For users, None.

 * This change will make it easier to understand the errors introduced by branches in progress.

[Test Case]

 * Open the results in the jenkins job and check the output and reports.

[Regression Potential]

 * autopkgtests could start failing. This will block the PR from merging into master, so we are covered.

Hello Leo, or anyone else affected,

Accepted snapcraft into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/snapcraft/2.12 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

There is nothing to verify in xenial-updates. I'm marking this as done.

Thanks Steve!
