Allow custom suffix when generating unit tests

Is your feature request related to a problem? Please describe it

We've settled with .test.ts as a unit-test suffix for all of our projects. While Nest is able to interpret these files, it can only produce .spec.ts files when generating a resource, which breaks our convention. It would be nice to be able to specify a custom suffix as a cli option.

Describe the solution you'd like

There should be a cli flag and config option to specify the suffix to be used, with the default being spec.

nest g res foo --spec-suffix=test

nest-cli.json:

{
	"generateOptions": {
		"spec": true,
		"specSuffix": "test"
	}
}

(flag and option naming TBD.)

What is the motivation / use case for changing the behavior?

Implementing this feature makes it easier to adopt company conventions.

Would you like to create a PR for this issue?

[garritfra]

@kamilmysliwiec I'll see what I can do.👍

[garritfra]

@kamilmysliwiec implementing this takes longer than I anticipated. To prepare for this change, I opened a draft PR in the schematics repo (nestjs/schematics#1077). Let me know if I'm taking a wrong route. Otherwise, I'll gradually finish that PR and then finish the work up here.

Thanks @garritfra, let's track this here nestjs/schematics#1077!

@kamilmysliwiec Does this need to be reopened? I don't believe the feature has been implemented and didn't make it into the cli as part of nestjs/schematics#1077

@garritfra Am I seeing that correctly?

[garritfra]

@hrkeni yes, that's correct. I don't have the time to work on it anymore, but it should be a simple change.

[hrkeni]

I would be happy to work on this.

@kamilmysliwiec Please reopen this issue and review PRs or let me know if I should open another issue here. Thank you.
