Known direct subclasses

ParentSandboxInvocationExecution, RemoteInvocationExecution, SandboxedInvocationExecution

ParentSandboxInvocationExecution	Version of `InvocationExecution` for the parent invocation special actions when running a sandbox.
RemoteInvocationExecution	Implementation of `InvocationExecution` that drives a remote execution.
SandboxedInvocationExecution	Special sandbox execution of the invocation: This is the InvocationExection for when we are inside the sandbox running the command.

Class that describes all the invocation steps: build download, target_prep, run tests, clean up. Can be extended to override the default behavior of some steps. Order of the steps is driven by TestInvocation.
