What's in this PR?

This PR enables buzz-adapter to be installed for Buzz client ^0.17.2.

Why?

Some of us are still stuck with Buzz 0.17.2 and we are not able to upgrade to ~1.0. Due to semantic versioning buzz-adapter version constraint ^0.15.2 won't allow Buzz 0.17.

looking at https://travis-ci.org/php-http/buzz-adapter/jobs/646883269?utm_medium=notification&utm_source=github_status there seems to be a problem with calling a non-existing method Buzz\Client\FileGetContents::setMaxRedirects - can you check what is happening there?

[MarioBlazek]

I have checked the problem. Looks like that Buzz 0.17 went very much forward with features, the setMaxRedirects was dropped in favour of OptionsResolver, for example.

@dbu do you think is it worth updating buzz-adapter to support 0.17?

[dbu]

afaik @Nyholm is involved quite a bit with buzz, maybe he can say what he things would make sense?

[Nyholm]

Buzz 1.0 supports HTTPlug 1 and 2.
Im not sure about the diff between 0.15 and 0.17, But it makes sense that setMaxRedirects was removed to support proper config values.

Im not sure what features 0.17 brings over 0.15. ie, why would you update?

[MarioBlazek]

@Nyholm current project is locked on Buzz 0.17, and I would like to add HTTPlug. But this looks like a big change to support 0.17.

Upgrading my project dependencies to support Buzz 1.0 would be a better choice, in my opinion. What do you think @Nyholm?

[Nyholm]

But this looks like a big change to support 0.17.

Im not sure. It is just a minor BC breaks from what I can recall. It may be possible (with just a few lines of code) to add support for 0.17 too.

OR, one can release a new major version of this Buzz adapter to only support 0.15.

Upgrading my project dependencies to support Buzz 1.0 would be a better choice, in my opinion. What do you think @Nyholm?

Yes, that is where I would spend my time.

[MarioBlazek]

Will focus on upgrading to Buzz 1.0 then. Thank you @dbu and @Nyholm
