ux(dashboard): lots of tweaks and polish to row menu, added remove X to add panel and row option views, #6442

Restores ability to change constant templates without going into
templating menu

Added two hints to help newer users

Added vertical ellipses, played with box shadows and borders and such. Ellipses need to fade to Opacity 0 when menu is open.

closes #6456

Fixed multi-value nested templating for opentsdb

* feat(alertlist): max-height to respect row height

closes #6417

* feat(alertlist): use pre calculated panel.height instead

* style(alertlist): rearrange variable order

This should be refactored. lets return condition results instead
of setting new value on the evalContext. The condition execution
should only be able to update its own state.

closes #6449

Log bad alert config and fixed alert message typo

Fixed intervalFormat for Graphite Alerting
