Use only a single thread

[hjr3]

This is testing much faster than using multiple threads (due to the lack of mutex lock contention for the pool). I was also able to remove rustful from the management API scope so we only have one version of hyper.

I have a few open items to fix:

• [x] fix health checks
• [x] finish storing stats
• [x] fix/remove test-server.rs

[yanns]

Can we also remove the dependencies.rustful dependency in cargo.toml?

[hjr3]

@yanns the test-server.rs code uses rustful. i added a note to fix or remove that so we can remove the rustful dependency.

[yanns]

@hjr3 OK thx for the explanation. Then we can at least move the dependency to dev-dependencies. rustful?

[hjr3]

@yanns yes, I will either move the rustful dep to dev-deps or remove the need for the dep prior to merge.

[hjr3]

one step closer!
