kubernetes compatibility matrix

[julienlau]

Hi,

Would it be please possible to add a kubernetes compatibility matrix to the documenation ?

In addition if some features are more stable than other, maybe a feature stability matrix would be nice ?

I did not try the addon yet, but the fact that this is young project makes it a hard choice to go to production with it.

I discovered the project through ceph user list, but I found no clue of this addons in the doc of ceph-csi... that's a shame ! It maybe a good idea to link both project a bit more in order to make it more well known ?

Thanks and regards Julien
