v0.3.0

This release changes the way you construct a uaa.API using uaa.New, and implements the functional options pattern (#25).

Breaking Changes:

• uaa.New(target string, authOpt AuthenticationOption, opts ...Option) removed zoneID, and added a new required argument (a uaa.AuthenticationOption) (and also additional optional uaa.Option arguments)
• Remove constructors:
  • Remove uaa.NewWithClientCredentials
  • Remove uaa.NewWithPasswordCredentials
  • Remove uaa.NewWithAuthorizationCode
  • Remove uaa.NewWithRefreshToken
  • Remove uaa.NewWithToken
• Remove uaa.API builders:
  • Remove uaa.API.WithClient
  • Remove uaa.API.WithSkipSSLValidation
  • Remove uaa.API.WithClientCredentials
  • Remove uaa.API.WithPasswordCredentials
  • Remove uaa.API.WithAuthorizationCode
  • Remove uaa.API.WithRefreshToken
  • Remove uaa.API.WithToken
• Rename uaa.API.AuthenticatedClient > uaa.API.Client
• Unexport uaa.API fields:
  • Remove uaa.API.UnauthenticatedClient (use the uaa.WithClient option instead)
  • Remove uaa.API.ZoneID (use the uaa.WithZoneID option instead)
  • Remove uaa.API.Verbose (use the uaa.WithVerbosity option instead)
  • Remove uaa.API.UserAgent (use the uaa.WithUserAgent option instead)
