[CLI] Improve error messages related to k8s connectivity

Description

Cli version

ProjectName: everestctl Version: v0.0.0-1471f784 FullCommit: 1471f784cd02951c05e5ee48c305953ada57508c

There are some scenarios for which cli doesn’t display any errors for install command. If the kubeconfig is not available, cluster configuration is incorrect or cluster can’t be connected to, then cli will just exit and display no errors

./bin/everestctl install --version-metadata-url https://check-dev.percona.com --version 0.0.0

I was able collect some errors using debug logging

Kubeconfig is not available

Could not connect to kubernetes cluster

Please check if there may are more scenarios. We should add similar error messages in upgrade/uninstall commands also.

Now cli is displaying error messages for various scenarios

Since cli is displaying error messages, hence closing this issue.
