Give write permission to e2e-tests task

[tkdchen]

STONEBLD-1832

Pull secret is required to be available for the e2e tests in order to
fetch image data from registry.redhat.io. The task needs the capability
in order to write the registry authentication credential into auth file.

Pull secret is required to be available for the e2e tests in order to fetch image data from registry.redhat.io.

How is that related to the changes in this PR?

[tkdchen]

The pull secret has to be written into the default auth file. What I found is, without the capability, it fails to write.

[mmorhun]

@tkdchen it would be nice to have the above in PR description. A link to docs or your findings would be a bonus.

[tkdchen]

@mmorhun Updated the commit message, PTAL. Also, rebased.

[mkosiarc]

Would it be better to change the short commit message as well? Instead of "Run e2e tests to check including parent sources" to "Give the e2e-test task write permissions" or something about updating the permissions?
