Add configurations for multi-API Angular apps

When connecting to several LoopBack APIs from an Angular app,
multiple definitions of LoopBackAuth and LoopBackResource will
'step on' each other, resulting in unpredictable behavior.

This change keeps the default behavior consistent, but will omit
the module block that generates the LoopBackAuth,
LoopBackAuthRequestInterceptor, and LoopBackResource
components if a fourth truthy parameter (excludeCommonModules) is
passed to generateServices.

This will enable loopback-sdk-angular to more seamlessly be used with
multiple-API architectures, without having to manually delete sections
sections of code generated by the SDK.
