Sys Props on the scheduler carry forward to executors

[kensipe]

• ability to map properties to maps
• ability to filter maps by what the key starts with
• sys props on the scheduler are carried forward to the executors
• several tests added

@gabrielhartmann @elingg looking for more love. I still need to test this on dcos. It looks like add we need. following that test I will refactor some xml (remove values) and add docs. ENV vars should be the preferred way to configure several things (like framework name, etc). I will also add docs + update universe with new approach.

Thank you, @kensipe! Began the review at least. See my above comments.

@elingg I took a different approach with predicates which I think resolves all of your list concerns, removes some code and feels better in general.

@elingg @gabrielhartmann looking for another review. I've tested this it works HOWEVER...

• the system works without configuration
• the system can read the system env configuration and make adjustments
• testing changing the framework-name has issues that I would like to resolve but seem outside of this PR and JIRA task.

Let me take a look @kensipe

I like this approach much better @kensipe! Looks pretty awesome. A few small comments above. Also please test on pure Mesos as we discussed to make sure the framework-name setting works as a sanity check.

[kensipe]

ok... all feedback applied. I'm getting ready to test on standard mesos. if good.. I will merge.

Sounds good
