Change default endpoint-id to be "default"

Previously this defaulted to the value of the container-id, but using
"default" makes the feature behave more closely to the existing
global-service-id feature.

Previously you needed to write:

  <endpoint endpoint-id="default" container-id="qrs" />

to mirror the existing behavior.  Now you can do

  <endpoint container-id="qrs" />

to get the same behavior.
