[BUGFIX] Fixing integration test failures.

[alexsherstinsky]

Scope

We have had consistent failures from two tests involving image processing. Through troubleshooting, the cause was determined to be the running out of storage space on the test host Linux machine in GitHub actions. The fixes are:

1. Improve error handling in Carton utilities module.
2. Add GitHub Action steps to clean out unneeded storage space.

Code Pull Requests

Please provide the following:

• a clear explanation of what your code does
• if applicable, a reference to an issue
• a reproducible test for your PR (code, config and data sample)

Documentation Pull Requests

Note that the documentation HTML files are in docs/ while the Markdown sources are in mkdocs/docs.

If you are proposing a modification to the documentation you should change only the Markdown files.

api.md is automatically generated from the docstrings in the code, so if you want to change something in that file, first modify ludwig/api.py docstring, then run mkdocs/code_docs_autogen.py, which will create mkdocs/docs/api.md .
