feat(library): add ServiceFromBuildContainer()

[jbrockopp]

Essentially a copy of #205

This adds a ServiceFromBuildContainer() function to the github.com/go-vela/types/library package:

types/library/service.go

Lines 503 to 528 in 240fd4a

	// ServiceFromBuildContainer creates a new Service based on a Build and pipeline Container.
	func ServiceFromBuildContainer(build *Build, ctn *pipeline.Container) *Service {
	// create new service type we want to return
	s := new(Service)
	// default status to Pending
	s.SetStatus(constants.StatusPending)
	// copy fields from build
	if build != nil {
	// set values from the build
	s.SetHost(build.GetHost())
	s.SetRuntime(build.GetRuntime())
	s.SetDistribution(build.GetDistribution())
	}
	// copy fields from container
	if ctn != nil && ctn.Name != "" {
	// set values from the container
	s.SetName(ctn.Name)
	s.SetNumber(ctn.Number)
	s.SetImage(ctn.Image)
	}
	return s
	}

Similar to StepFromBuildContainer(), that was added in the above PR, this will be used in the go-vela/worker codebase.

Also, following along with the above PR, ServiceFromContainer was renamed to ServiceFromContainerEnvironment.
