Dashboard UI 1.0.0 release

Update validation message

Add links to tour on zerostate and deploy views

Move metric units to table header to save space and disambiguate

With that we'll not have `kcores` (kilo-cores) neither `TCPU`
(tera-CPU). This also saves space since all numbers in a column have the
same unit.

Fixes #405

Fix overlaping error message and remove huge padding under name input

Label Key validation on Deploy page

Clarify how users can change apiserver-host in canary deployment

Add container image validation

Small layout fix for IE11

With this there is no jitter and overlap

Fixes #477

Fixes #484

deploy from file integration tests added

Fixed issue with unit test fail on IE

Added directive to validate different types on input field values

Fix layout isses where deploy form container shrinks

Make docker build pipeline always use clean env and actaully work

Previously it didn't always work because my local env was overriding
what was previously baked into image. Now the image bases only on source
code and is brand new each time.

It is also a lot faster when dockerignore excludes more files.

Updated/added links to additional documentation

Fixed deploy from file on IE

Redirect to zerostate if there are only RCs in namespace "kube-system"

upgrade to latest heapster version to make the sparklines work

Fix flaky tests

Show link to RC list in zerostate when there are only RCs in namespace "kube-system"
