Update library state info to content library API

Add the optional state info and server guid to Library type, both fields
are the info for read only (get API), also update the fields to the
library simulator and example test accordingly.

Testing Done:

=== RUN   TestManagerCreateLibrary
created library example
--- PASS: TestManagerCreateLibrary (0.36s)
PASS
