Add documentation on how to create a DNS entry - docs
We should add documentation with basic instructions on how to create a DNS entry for GitLab. This will become more important for users when we have instant SSL support via Let's Encrypt, as well as helpful for our less technical users.
The documentation should include:
- General information on DNS, and why it's important. (Easy to remember, required for SSL)
- The two options: wildcard and specific records. Details on what we require for each.
- Links to DNS configuration information for the major providers
- GoDaddy, Google, Amazon, 1&1
- Next steps, like links on how to set up additional things with their own DNS names like the registry, pages, etc.
