M16 Rebase

[jezdez]

I've rebased on top of the recent Redash repo and pushed a m16-rebase branch to our fork repo:

getredash/redash@master...mozilla:m16-rebase

Commits removed

Because the features were fixed or ported upstream:

• accommodate '/' in dashboard tags (re There is no tag on the left for "Activity Stream A/B Testing" #48) 7d43c5a
• reject non-list dashboard layouts (re Dashboard showing up empty after hitting "publish" #25) 31358be
• Reject empty names for dashboards (re A dashboard name can be removed completely #76) d4813e4
• allow unpublished queries to be used as alerts (re Show user's unpublished queries in dashboard 'Add Widget' search #97) cf7f8cf
• adding activedata query_runner (re Add an ActiveData query runner #83) c1f01d9
• Re-prompt for login if an unauthorized Google account is used (fixes Improve wrong domain auth message #79) f33416c
• change pie chart colors (re Pie Chart not working? #240) db948e5 (Pie chart: sectors colors getredash/redash#2616)

Commits combined

Since they were adding to the code churn

• all Circle CI and deploy specific changes
• datasource health extension commits (adding and removing)

Reopening since there are a few bugs

We've fixed the bugs that @madalincm reported in the m16-rebase branch and pushed it to release.
