Document snake_case conversion by ansible operator

[cpitman]

Description of the change:

Added documentation around the handling of variable names by the ansible operator. Previously the only way to know how this works was to read the code.

Hi @cpitman. Thanks for your PR.

I'm waiting for a operator-framework member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

I understand the commands that are listed here.
