Zaqar's test suite is quite flexible, it allows for setting up custom config files that point to other servers and whatnot. However, from a packaging perspective, this is far too much and there are no other (simpler) options that would allow for setting a custom db uri from the shell.

Add a `ZAQAR_TEST_MESSAGE_STORAGE_URI` and `ZAQAR_TEST_MANAGEMENT_STORE_URI` that would allow for dynamically change the uri depending on the environment.
