Ability to provide a test timeout for every test in a session.

[AbhitejJohn]

Description

Currently the timeout for a test is only an attribute apply-able on a test method in code. This cannot be changed without a rebuild of the test code. This request is to add a configurable timeout for each test in a session. This can be achieved via an additional setting in the runsettings section for the adapter like below:

<Runsettings>
   <MSTest>
      <TestTimeout>2000</TestTimeout>
   </MSTest>
</Runsettings>

So when the above runsettings is provided in a session, every test in that session can run for a maximum of 2000 milliseconds.

Few spec questions before implementing this:

1. What would happen if a test has its own timeout defined via the Timeout attribute? Which takes precedence?
2. All tests running in a session would now become time bound. Can/should a test opt-out?

1. the attribute farthest to the method will win.
2. if a method wants to, it can set a custom time out for itself, but (1) would still apply.

Any ETA on this?

It looks like this is just about done in #403. So look forward to NuGet 1.3.0 to have it?

@AdamDotNet Can confirm this is present in 1.3.2 at least, docs still don't reflect it though.
