vm factory UX enhancements

[bergwolf]

As #303 only targets to get the core part of vm factory landed, there are a few UX-related enhancements that I've been pushing back, and it would be great to look at them after #303 is merged. This issue is to collect and track these enhancements.

• 1. kata-runtime factory status checks and prints the vm factory status - by @grahamwhaley
• 2. enable_debug for vm factory config section - by @jodh-intel
• 3. document security implications of vm templating (possibly we can combine this with documentation/issues/167) - by @amshinde
• 4. kata-runtime create automatically creates vm factory if it does not exists yet - by @WeiZhang555

Please feel free to comment on the details or if you have more in mind. Thanks!

Hi @bergwolf - happy to pick up that debug task, but I'm not actually sure what needs to be done - do we actually need a new option?

[bergwolf]

@jodh-intel oops, I just had it done this afternoon... posting PR soon. We don't need a new option, but a new API to let vm factory use the same logger.

@jodh-intel see #521. I was working on something else today and found out that vm factory logger is not working so I fixed it. I haven't started the rest two. If you want to help with that, please feel free to do so and I won't step on your toes again. sry...

No problem - I love it when work disappears like that! 😄
