* Wrap warning messages to make them more visible
For example, instead of displaying:
```
⚠ You are using "default" project, odo may not work as expected in the default project.
```
We are now displaying:
```
========================================================================================
⚠ You are using "default" project, odo may not work as expected in the default project.
========================================================================================
```
* Display warning message about default project/namespace in a single block
* Add unit test
* Fix sample outputs for doc automation tests
* Revert "Fix sample outputs for doc automation tests"
This reverts commit 98a6554c34.
* Ignore '===' warning header and footer for doc automation tests
