This is a pass through test failures and deprecation warnings:
* Make all ambiguous `.with(..., key: val)` use explicit hashes to
prevent test failures for argument mismatch in Ruby 3.0
* Scope down all unbounded `raise_error` to address warnings (remove
one test that was revealed to be referencing a nonexistent variable
once the raise_error was scoped.)
* Update all `any_instance` usage to new syntax to address warnings
* Allow the service cache to be cleared and do so between some tests
* Fix a small bug in with_plugin's plugin not found code path (revealed
by a scoped and_raise)
The IsRunning action checks if `env[:machine].state.id == :running` but
this check was never passing as the protobuf-washed version of machine
state was yielding a machine state w/ a string value like `"running"`.
Easy fix in the mapper!
Boolean types (and possibly a few others) are returned as wrapper
classes when coming out from proto mapping; these need to be unwrapped
otherwise the caller who is expecting a nice clean boolean value ends up
with an icky protobuf class.
This fixes the shell provisioner, which relies on a communicator
receiving a settings hash `{error_check: false}` for a command that
usually fails but it sent just in case before provisioning starts.
