Add Discord rules

These rules are currently implemented using the rules screening feature
of Discord. However, I haven't found an obvious way to view them for
people who have already joined the server.

+# Discord Rules
+
+1. This community works together to build an Open Source BMC firmware. It's a
+   community expectation that you will provide access to your code in the course
+   of discussions. We are unable to build together if you are unable to share
+   your code. The community is not a substitute for a support contract.
+
+2. OpenBMC community members are volunteering their time to answer your
+   questions. Please keep this in mind if you are waiting for a response.
+
+3. All support questions must be asked in public channels. Do not send uninvited
+   private messages to other community members. Private requests for help place
+   an unfair burden of expectation on people volunteering their time. Further,
+   others in the community cannot help if they cannot see the question.
+
+4. Don't post the same question in multiple channels. Doing so fragments the
+   conversation. If you're unsure of which channel to use, ask your question in
+   `#general` and we may redirect you elsewhere.
+
+5. Reflect on whether your standing in the community is appropriate for the help
+   you are requesting. If you are new to the community, you will likely have the
+   most success by asking detailed, specific questions about detailed, specific
+   problems. Vague questions by unfamiliar people often go unanswered
+
+6. Do not discuss undisclosed bugs that may have a security impact in Discord.
+   Instead, email `openbmc-security@lists.ozlabs.org` and follow the [documented
+   directions][1]
