Add issue template

[rachael-phillips]

I would like to add an issue template for our contributors.

issue: #2788

[tlabaj]

is this block needed?

[rachael-phillips]

No, I don't think so.

[tlabaj]

Suggested change

	### Describe the issue. What are the expected and unexpected behavior categories?
	### Describe the issue. Including the expected and unexpected behavior

[tlabaj]

Can we also add a question "is there a workaround?"

[rachael-phillips]

Yes, and maybe we wrap that into @redallen 's question about it being blocking. What about "If this issue is a bug, Is this issue blocking you or is there a work around?" cc @dgutride

[redallen]

I suggest we go with something closer to what React has. I've replaced "React" with "PatternFly" below and am open to feedback.

**Do you want to request a *feature* or report a *bug*?**

**What is the current behavior?**

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than PatternFly and React. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below:**

**What is the expected behavior?**

**Which versions of PatternFly, and which browser are affected by this issue? Did this work in previous versions of PatternFly?**

Then we could also add:

**If working on a Red Hat product, which product is this affecting and is there a workaround for now?**

[redallen]

Could also ask if this is blocking product work.

[rachael-phillips]

What do you think about this feedback @tlabaj ?

[tlabaj]

I think the wording here is what the team agreed upon. This give us more insight into an actual timeline for when the feature is needed.

[redallen]

I don't like this wording. As a dev, I'm not sure what a behaviour "category" is.

[redallen]

I think this question should be asked first and read like "Is this a bug or feature request?"

[rachael-phillips]

@redallen we chose this wording because we felt it was most helpful for users who may not know what a feature request is. cc @tlabaj @dgutride

[tlabaj]

Maybe "Is this a bug or an enhancement?"

[redallen]

Love it ❤️ .

[jschuler]

Would be good to provide a ready-made environment that already pulls in PF etc

[redallen]

This is on my to-do list, especially with the -org refactor. You can add a followup issue and assign me!

[redallen]

This line needs to be commented. Also, please add this codesandbox link for people to easily reproduce issues: https://codesandbox.io/s/x2isc

[rachael-phillips]

What do you mean by it needs to be commented? It is just a general description of the template. I can add the link for sure.

[redallen]

I mean it needs to look like this:

<!-- Please populate the PatternFly issue template so we can learn more about your needs. Here's a codesandbox link you can reproduce your issue in: https://codesandbox.io/s/x2isc -->

The <!-- --> makes it a comment that won't appear as plain text inside the issue.
