This PR updates the tags that we generate for Envoy stats.
Several of these come with breaking changes, since we can't keep two stats prefixes for a filter.
* ui: Add functionality to metrics mocks:
1. More randomness during blocking queries
2. NaN and undefined values that come from prometheus
3. General trivial amends to bring things closer to the style of the
project
* Provider should always provide data as a string or undefined
* Use a placeholder `-` if the metrics endpoint responds with undefined data
* Remove local httpGet and shim one in from options
* Add custom httpGet to pass through to provider
* Make a fetch wrapper that adds your token
* Pass the fetch like fetchWithToken wrapper through to the provider
* Fix up httpGet to encode query params again and use fetch-like
* Plumb Datacenter and Namespace to metrics provider in preparation for them being usable.
* Move metrics loader/status to a new component and show reason for being disabled.
* Remove stray console.log
* Rebuild AssetFS to resolve conflicts
* Yarn upgrade
* mend
* ui: Add the most basic workspace root in /ui
* We already have a LICENSE file in the repository root
* Change directory path in build scripts ui-v2 -> ui
* Make yarn install flags configurable from elsewhere
* Minimal workspace root makefile
* Call the new docker specific target
* Update yarn in the docker build image
* Reconfigure the netlify target and move to the higher makefile
* Move ui-v2 -> ui/packages/consul-ui
