* CSS for moving from a horizontal main menu to a side/vertical one
* Add <App /> Component and rearrange <HashcorpConsul /> to use it
1. HashicorpConsul now uses <App />
2. <App /> is now translated and adds 'skip to main content' functionality
3. Adds ember-in-viewport addon in order to visibly hide main navigation
items in order to take them out of focus/tabbing
4. Slight amends to the dom service while I was there
Adds a 'status' for the filtering/searching in the UI, without this its not super clear that you are filtering a recordset due to the menu selections being hidden once closed. You can also use the pills in this status view to delete individual filters.
* ui: Install ember-intl
Also:
1. Removes our own format-number in order to use ember-intl's instead
2. Moves format-time to format-short-time so as to not clash with
ember-intls own format-time
