* functions: application updates no longer accept name in the body
AppUpdate was initially conceived as an upsert endpoint for apps.
It turns out that it created an inconsistency regarding updates:
updates with names divergent with URL would not actually change
application's name.
This commit atempts to address the issue by returning an HTTP
error when trying to update an application name. In swagger.yml,
application names are already `readOnly:true`. Thus there is no
change from expected behavior.
Fixes#380
* functions: use specific error value for name change
Ensure that attempts to update route's path are properly handled
with a HTTP error. Moreover, updates swagger file to make it
explicit that routes are immutable.
Fixes#381
* functions: modify datastore to accomodate hot containers support
* functions: protocol between functions and hot containers
* functions: add hot containers clockwork
* fn: add hot containers support
* fn: make UX more consistent with regards to app name position
