Create a tcp component

[piraz]

Let's create a TCP component to facilitate the creation of servers without the whole HTTP stack on it.

Those kind of components would be great to create simple agents and servers where handlers are not a requirement.

We could review the schedule structure because schedulers are designed to trigger jobs and handlers are there just because the schedule component inherits from the tornado component, that will create a whole HTTP server.
