Add GitHub issue templates for bug reports and feature requests (#1009)

We currently do not have GitHub issue templates when 
the community creates issues. Having issue templates
would aid us in catching relevant information that would
help in faster resolution of those issues reported.

With this PR, we're are adding issue templates for bug 
reports and feature requests.

closes: #977
