Define "sensitive data" in the context of resource usage for applicants

[RobertKielty]

In the Usage Guidelines given to open source developers on the README in this repo we have the following statement

| Code being run must be 100 percent open source and must not include any sensitive data.

(emphasis added)

We have been asked to provide a definition of sensitive data by @LucaGuerra from the Falco Project

As the question raised is not project-specific and relevant to the entire community I'm raising the issue here.

The two obvious areas to consider wrt to sensitive data are

• private keys associated with service access
• personally identifiable information

@jeefy PTAL and let us know how we would like to define sensitive data for the applicants

FYI @lukaszgryglicki I reviewed

https://github.com/cncf/cluster/blob/b80b8a9b953c3ad3a65b0276970bf73b547eaa10/TERMS_OF_USE.md

It is a useful document wrt defining prohibited and unacceptable uses of the resources in the lab.
