Move impl of identity.GetAccounts() extension API to its own file

Move impl of identity.GetAccounts() extension API to its own file

As a precursor to a refactoring of the identity extension API implementation
to use the Identity Service, I am moving the implementations of the six
identity extension API functions to their own files, rather than all
being lumped together in identity_api.*. This will make it easier to
analyze each of these function implementations independently and
incrementally convert them to use the Identity Service.
