I've gone through all the TODOs in the container module (except the VFS)
and created JIRA issues for them. I also updated the source with the JIRA issue.
There are some TODOs that are just reminders that some of the test utility methods
need promoting to the AbstractTestCase class in the test module
which I haven't updated.
There is nothing major in these TODOs they are all mainly just tidyup.
