Recover driver list from gRPC and not have a fixed list

[mcuadros]

We should recover the list of driver installed on the server and the versions, instead of the hardcoded list.

[smacker]

Do you think we should add method to client-go or call bblfshd gRPC directly from dashboard?

[mcuadros]

The better will be call to gRPC: https://godoc.org/github.com/bblfsh/bblfshd/daemon/protocol, otherwise you will need to parse an ASCII table.

In this case we will need use dep because this API is not versioned.

[smacker]

Let's wait for decision about this proposal first: https://github.com/bblfsh/client-go/pull/32

As soon as bblfsh/client-go#32 is merged now and before adding new drivers at #119 let's move forward with this.

@dpordomingo would you mind adding it to Applications project, so it shows up on our backlog? Thanks in advance!
