Add support for Sysdig Secure compliance tasks

[meskio]

As well as adding support to fetch policy events by id.

LGTM besides a couple of comments. Nice work, thank you for the refactor.

I've seen this a couple of times at the code. Would this be worthy?

options = {
    'name': name,
    'moduleName': module_name,
...
}

for key, value in options.items():
    if value is not None:
        task[key] = value

I'm not sure how readable are dict completions, but this is a try: 33e82b2

[figarocorso]

Yeah, totally right. Wasn't sure at all, but wanted to know your opinion ;-)

@meskio unfortunately this time the build was failing for real:

Would you mind taking a look and see if you can file another PR to fix the test (or code)? Let me know if you need any help.

Thanks!

Ouch, I thought I tested. I'm looking into that.
