The default 'open files' limit, 1024, is way too low for some of our applications. Since there's no way to bump this limit from within a container, and the artificial limit of 1024 file descriptors stems from an era where FDs were costly, bump the limit to a more reasonable (in 2019) default. Fixes: #1785 See: #1785 See: containerd/containerd#3201 See: containerd/containerd#3202
