Bump Helm to v2.10.0

Ran `glide update` and `glide install --strip-vendor`.
Added version specifications to k8s.io/apimachienery and k8s.io/apiserver according to helm's glide.lock https://github.com/helm/helm/blob/cc7cc1087f586f64d0b0d08aa516a003ced2d85b/glide.lock#L457 to prevent build errors.

The huge k8s.io/kubernetes dependency is introduced due to the upstream issue, helm/helm#4499.
It should be changed to our own fork, and the removed in the future once the upstream incorporates the fix.

Resolves #81
