Refine prompts and output

[beatfactor]

Renamed most of the prompts to match a more active voice and tone in order to simplify the onboarding process overall. This is also according to our own documentation style guide, namely:

• Use active voice. Think of it as you being the guiding teacher to the user
• Be in the present
• Write short sentences that are crisp and concise

Changes reflect a more imperative style:

• prompts present commands instead of questions which look like things to do rather than decisions to take
• impersonal approach ("your" / "my" is removed from the text)

New onboarding process:

-  Select language + test runner variant
   - JavaScript / default 
   - TypeScript / default 
   - JavaScript / Mocha 
   - JavaScript / CucumberJS  
- Select target browsers
- Enter source folder where test files are stored (test)
- Enter the base_url of the project (http://localhost)
- Select where to run Nightwatch tests (Use arrow keys)
  -  On localhost 
  - On a remote/cloud service 
  - Both  
- Allow Nightwatch to collect completely anonymous usage metrics? (y/N) 
-  Setup testing on Mobile devices as well? 

Other changes:

• refactored template tests
• refactored tests to be compatible with Mocha

The only prompt which I am not very sure of is "Select where to run Nightwatch tests"; to users who aren't familiar with Selenium or cloud testing services this prompt will most likely be confusing. We should probably change it to be similar to the one for mobile testing setup, e.g.:

- Setup Nightwatch to connect to a remote testing service?
   - No, skip for now (default)
   - Yes

Skipping GitHub is intentional here? Since the comment above still mentions GitHub.

[beatfactor]

Yes, displaying the Github link adds no real value to the output.

I think chromedriver and mocha are not required in this project as a dependency.

[beatfactor]

I'm using mocha to run the tests, in addition to nightwatch.

[beatfactor]

At the moment there is only one test failing if you run it with mocha and I think that having mocha as an option to run the unit tests locally it's useful.

updated browsers prompt.

Suggested change

	if (answers.backend === 'local' && process.platform !== 'darwin') {
	if (process.platform !== 'darwin') {

But this will also remove 'Safari' for users who want to test on Safari browser on remote/cloud service from Windows/Linux machine.

Maybe we can just remove this if block so that 'Safari' appears everytime, or if the user's system is non-mac, we can change the option to something like 'Safari (cloud only)'?

[beatfactor]

Adding Safari (cloud only) will only complicate things further because we have to handle the case where you select Safari and do not select cloud. So I think for now it's ok to just show Safari for Mac because advanced users who want to test on cloud safari can always add the config manually.

[garg3133]

The case of selecting Safari and then not selecting cloud is already handled though, in refineAnswers method.
(refineAnswers is written in a way that even if there are discrepancies in the input answers, the output should always be in the right format.)

But I am okay with both approaches.

[beatfactor]

so an error will already be thrown?

[garg3133]

No, 'safari' is silently removed from local browsers list if the user is on a non-mac machine.

@vishalshah133 any thoughts here? this would be needed to be merged as @harshit-bs is already working on adding support for component testing.

[garg3133]

LGTM! Just waiting on @vishalshah133 to review the questions flow once.
