Add issue templates (#37)

Add templates for issue creation. Because we still do not have a
discuss, all links still point to Beats discuss.

A `.gitignore` file is also added.

+Hey, stop right there!
+
+We use GitHub to track feature requests and bug reports. Please do not
+submit issues for questions about how to use features of Beat, how to
+set Beats up, best practices, or development related help.
+
+However, we do want to help! Head on over to our official Elastic-Agent-Inputs forums and ask
+your questions there. In additional to awesome, knowledgeable community
+contributors, core Elastic-Agent-Inputs developers are on the forums every single day to help
+you out.
+
+The forums are here: https://discuss.elastic.co/c/elastic-stack/elastic-agent
+
+We can't stop you from opening an issue here, but it will likely
+linger without a response for days or weeks before it is closed and we
+ask you to join us on the forums instead. Save yourself the time, and
+ask on the forums today.
