[e2e] Cleanup ermine_session_shell_test.
Add a README.md file with some explanations about how
e2e product tests are configured.
As a consequence of such configuration conventions, e2e tests
should be added more directly to product build specs, and the
intermediate build package for end_to_end tests should be
deleted. Cannot be done directly since it requires cross repo
coordination.

+# End to end product tests
+
+End to end product tests for fuchsia products that contain ermine are located
+here.
+
+More end to end product tests for products in [`fuchsia.git`][1] are found in
+[`//src/tests/end_to_end/`][2].
+
+Unlike other kinds of tests, end to end product tests are specific to a product,
+and therefore must not be included in the global `tests` build target mandated
+by the [source tree layout][3]. Instead, end to end product tests are included
+directly in the build configuration of their products in [//products][4].
