feature: case-insensitive "digger" in comment ops

[dannysauer]

I wasn't paying attention while working on mobile, and my phone keyboard defaults to upper-casing the first letter typed in a field like it's a sentence, which isn't valid. It's a trivial thing, but perhaps the comment prefix could be compared with case-insensitivity. That may be as simple as updating this line:

digger/backend/controllers/github.go

Line 738 in bbc1931

if !strings.HasPrefix(*payload.Comment.Body, "digger") {

Looks like the command parser is already forcing to lowercase.

digger/libs/scheduler/utils.go

Lines 26 to 42 in bbc1931

	func GetCommandFromComment(comment string) (*DiggerCommand, error) {
	supportedCommands := map[string]DiggerCommand{
	"digger noop": DiggerCommandNoop,
	"digger plan": DiggerCommandPlan,
	"digger apply": DiggerCommandApply,
	"digger unlock": DiggerCommandUnlock,
	"digger lock": DiggerCommandLock,
	}
	diggerCommand := strings.ToLower(comment)
	diggerCommand = strings.TrimSpace(diggerCommand)
	for command, value := range supportedCommands {
	if strings.HasPrefix(diggerCommand, command) {
	return &value, nil
	}
	}
	return nil, fmt.Errorf("Unrecognised command: %v", comment)
	}
