add kafka 1.0.0 to travis and as kafka version constant

[buyology]

fixes #983

anything I'm overlooking atm?

strictly speaking I guess the version is V1_0_0 rather than V1_0_0_0 now that it has moved to 1.*. should we keep it for symmetry though?

xref #985 (comment)

should we also

• remove 0.9?
• bump 0.11.0.1 to 0.11.0.2?

Ya, especially since there's a bunch of logic that assumes all versions have four places and would break if we changed it to three.

Update the compat section of the README?

remove 0.9?
bump 0.11.0.1 to 0.11.0.2?

Yes please. 0.9 is well out of our 2+2 window, I've just been lazy about removing it.

Thanks!
