Issue DM-5156: Please document MemoryTestCase
{{lsst.utils.tests.MemoryTestCase}} is used extensively throughout our test suite, but it is lacking in documentation and it's not clear under what circumstances its use is required or encouraged. Please add appropriate documentation to the [Software Unit Test Policy |http://developer.lsst.io/en/latest/coding/unit_test_policy.html]. See also [this thread on clo|https://community.lsst.org/t/what-is-the-policy-for-using-lsst-utils-tests-memorytestcase].
