Optimize relative time creation

Not using the plugin from within the AngularJS directive
is faster, as we can directly use the data, without having to
read it off the DOM, etc.

Not initializing tooltips also helps.
Optimize service status badge rendering

This makes it 4x faster. Rendering 90 status badges
used to take 200ms. Now down to 50ms.
Only create avatar tooltips on initial interaction
Optimize services list table
Do not show host name on each service list row

It's shown above the table anyway. Showing it again wastes space.
Fix time relativization

We used to replace the whole <time> element within,
which is not what we want, because we need
to allow re-relativization later.
Optimize service index layout page - reduce jumpiness
Build the services/logs views incrementally

Do this by rendering a small subset of all the data first,
and then expanding that.
Upate devture/dbal - brings faster subsequent find() calls
Micro-optimizations in status parsing
Optimize objects retrieval from the Status Manager
Micro-optimizations for ApiModelBridge exporters
Use lazily-created Bootstrap tooltips for relativized times
