Upgrade to tokio 0.3

[djc]

Would be nice to have.

I just took a quick look, and it looks like Marwes/combine#302 would have to be addressed first, as that's a Tokio 0.2 dependency.

[djc]

Yes, I came to the same conclusion when I was looking at this.

[Austaras]

But combine has a feature flag for tokio 0.3?

[djc]

(Looks like this is being fixed over in #405.)

[RAnders00]

combine now has tokio 0.3 support in v4.4.0.

Well, now #378 didn't arrive in 0.17.x, but 0.18.x is incompatible with Tokio 0.2 that Actix uses 😞

[Marwes]

You can use https://github.com/LucioFranco/tokio-compat-02/ to use tokio 0.2 and 0.3 simultaneously @nazar-pc

Only works the other way around unfortunately. There is an issue in Actix about upgrading to 0.3, will use a git commit that includes above fix for the time being.
