Pipeline configurations generated from CHAPbook

[keara-soloway]

I think there are 2 small bugs in generating CHAP configurations from the notebook:

CHAPaaS/chap.go

Lines 179 to 194 in 99dabf2

	func genChapConfig(user, module, reader, writer string) string {
	config := "pipeline:\n"
	reader = strings.ToLower(reader)
	writer = strings.ToLower(writer)
	if reader == "yaml" {
	config += " - common.YAMLReader: {}"
	} else if reader == "nexus" {
	config += " - common.NexuReader: {}"
	}
	//config += " - UserProcessor: {}\n - common.PrintProcessor: {}"
	config += fmt.Sprintf(" - users.%s.%s.UserProcessor: {}\n", user, module)
	config += " - common.PrintProcessor: {}\n"
	if writer == "yaml" {
	config += " - common.YAMLWriter: {}"
	} else if writer == "nexus" {
	config += " - common.NexuWriter: {}"

Missing \n-s on L184, L186, L192, and L194, and NexusReader is missing an "s" on L186 and L194.

Here's what I see in CHAPbook: if I select a YAMLReader, put some code in the notebook for the UserProcessor, then click "Run", the output is this:

pipeline:
  - common.YAMLReader: {}  - users.keara-soloway.userprocessor.UserProcessor: {}
  - common.PrintProcessor: {}

(and similar for NexusReader).

@keara-soloway , it is fixed now in 2af6e21 commit.

but I didn't yet update lab server with this change.
