Previously tests would stop running on the first failure.
With this PR we move onto running the tests for the next module. This
allows DCI runs to have a fuller picture of what's broken.
This only effects manual and DCI runs, it doesn't effect Shippable runs
as this the modules are tested directly.
* eos_banner docs improvements
* run eos_banner tests
* basic eos_banner tests
* remove trailing newlines
* remove hack
* Various eos_banner fixes
No unicode tests, as the device doesn't support it
Correctly set provider
result.command should be empty list if no changes
* test eos_banner over eapi
* revert docs changes, moved to separate PR
