sqoopctl install kube installs old versions of k8s resources that fail on newer k8s versions:

we need to update to install newer versions of Gloo, that support k8s 1.16+

when I run sqoopctl install kube, it install very old version of gloo on the cluster (v0.13.25).

Suggestion: I know sqoop is a layer over gloo, so when I install sqoop that mean may I already have gloo installed, and I want sqoop to be installed over my gloo installation.

that mean making gloo as prerequisite to install sqoop,
and if we have compatibility problem you can display a message with the preferred version.
