Bazel DevSite: Add "create issue" & "view source" buttons to narrative documentation.

A future change will add the buttons to the reference docs (which is a bit more complex since there is no 1:1 relation between displayed page and source file).

 # Bazel Tutorial: Configure C++ Toolchains
 
+{% include "_buttons.html" %}
+
 This tutorial uses an example scenario to describe how to configure C++
 toolchains for a project. It's based on an
 [example C++ project](https://github.com/bazelbuild/examples/tree/master/cpp-tutorial/stage1)

 # Review the dependency graph
 
+{% include "_buttons.html" %}
+
 A successful build has all of its dependencies explicitly stated in the `BUILD`
 file. Bazel uses those statements to create the project's dependency graph,
 which enables accurate incremental builds.

 # Use labels to reference targets
 
+{% include "_buttons.html" %}
+
 In `BUILD` files and at the command line, Bazel uses *labels* to reference
 targets - for example, `//main:hello-world` or `//lib:hello-time`. Their syntax
 is:
