run-tests: move extra config options to Test.__init__

run-tests: refactor port number declaration Instead of making port numbers derived from count and a global initial port, we now pass a start port to Test.__init__ and do the calculation at a higher level.

run-tests: move timeout into Test.__init__

run-tests: move interactive to Test.__init__

run-tests: move diff options into arguments of Test.__init__

run-tests: move debug into an argument to Test.__init__

run-tests: factor options.keep_tmpdir into an argument to Test.__init__

run-tests: remove redundant test name filter TestSuite.run() doesn't need to filter tests by name because that already happens elsewhere. Garbage in garbage out applies.

run-tests: move test filtering into TestSuite.run() Upcoming patches will move the execution of tests to separate processes. To facilitate this, it makes sense to move logic out of Test. Furthermore, test filtering is logically the domain of the test runner, not the test itself. This patch interrupts our mini series of factoring options into named arguments because filtering consults many options and it is easier to move this logic out of Test sooner so we don't have to introduce arguments at all.

run-tests: no longer pass a TestRunner into Test.__init__ We no longer access any attributes on TestRunner besides options, so we stop passing a TestRunner to Test.__init__ and now pass the options data structure instead. Subsequent patches will move accessed options attributes into named arguments.
