Add ability to enable twistcli debug mode

[raoganeshr]

Currently some of the scans with this action take more than 4 minutes. I wanted to enable debug logs so that we can understand what is contributing to the delay. I believe twistlock does have a debug flag but I have not found a way to enable that using this action.

Can you add this feature and if already present add the steps to enable it to the readme for this action.

I'm not a contributor, but I'm afraid if you would like anything to be done in this direction you might need to do at least the minimum effort of verifying if such debug mode really exist in the cli:

I've found the docs for you: https://docs.prismacloud.io/en/classic/compute-admin-guide/tools/twistcli

@mikocot twistcli does have a --debug flag that logs much more details than what twistcli currently does as part of the action.
