Add bind:true option to getCurrentContext
Workaround issue #17 with cujojs/when v3.7.7 due to the fact
that it internally uses a mechanism of user-land queuing for
async-related operations, and possibly issues with similar
packages using queuing (mostly Promise libraries)
Rework the module to use the new cls-hooked module (which uses AsyncWrap
available since Node v4.5) instead of old continuation-local-storage
(based on very unreliable async-listener).
Rename "per-request-context" middleware to shorter "per-request".
Introduce "LoopBackContext.perRequest" as a shortcut for way too long
"loopback-context/server/middlewar/per-request"
