GH-1033 - Prevent dynamic agent attachment warnings caused by Mockito.

Prior to this commit, running our tests caused the following warning because Mockito was dynamically self-attaching to the running JVM:

Mockito is currently self-attaching to enable the inline-mock-maker. This will no longer work in future releases of the JDK. Please add Mockito as an agent to your build what is described in Mockito's documentation: https://javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/Mockito.html#0.3

We now follow the advice in the provided link and set up our build accordingly.
