load session (bar) and persistent (foo) cookies.

[lfg, 2017/02/15 22:44:00]

Done.

+// step2. Guest responds saying it has added cookies.
+// embedder clears cookie data of the guest via clearData API.

[lazyboy, 2017/02/15 21:45:26]

clears session cookie data...

[lfg, 2017/02/15 22:44:00]

Done.

+// step3. Ask guest for cookies that were set in step1.
+// step4. Guest responds with cookie values, embedder verifies they are unset.

[lazyboy, 2017/02/15 21:45:26]

verifies session cookie is unset but persistent cookie is still set.

Do the same for other test to update the step descriptions.

Here you want to note what this means. e.g. barValue is session so it's gone,
etc.
