This extends the kubectl segment to optionally not rely on the
kubectl command and instead to directly parse kubeconfig files like
kubectl does. This is meant as a performance optimization similar
to how the git segment can determine the current branch itself
without calling to git. Especially on Windows and in the presence
other factors slowing process creation like like AntiVirus this
can make shells using the segment considerably more responsive.
The functionality is enabled using the new parse_kubeconfig prop.
It defaults to false to prevent breaking existing users in case
there are any unanticipated behavioral changes.
Additionally the new template properties Cluster and User were
added as they are easily available and helpful in kubectl
setups with more elaborate configuration.
fix: align dotnet segment with other languages
feat: missing command text + json schema updated
chore: doc updated
perf: cache executable path
chore: not supported version icon updated(previus one was unreadable)
