Issue:
If users import the vmss info and then try to use --node or --id, then
the command will fail because we will have vmss info + node or vmss info
+ resource-id and it will not know what to select.
Solution:
Don't read the current config vmss info if node or id was specified. It
is not needed anyway.
Initial state:
$ ./kubectl-aks config import
Let's say aks-nodepool1-17267820-vmss000002 is the node I need to use more frequently:
$ ./kubectl-aks config use-node aks-nodepool1-17267820-vmss000002
However, if I need to run one single command in node aks-nodepool1-17267820-vmss000000
Before this PR:
$ ./kubectl-aks check-apiserver-connectivity --node
aks-nodepool1-17267820-vmss000000
Error: specify either 'node' or VMMS instance information ('subscription', 'node-resource-group', 'vmss' and 'instance-id')
After this PR:
$ ./kubectl-aks check-apiserver-connectivity --node
aks-nodepool1-17267820-vmss000000
Connectivity check: succeeded

`kubectl-aks` should use the node information from config file when available. Initial situation: $ ./kubectl-aks config import $ ./kubectl-aks config use-node aks-nodepool1-17267820-vmss000000 Node not available in the confi file will use the API server: $ ./kubectl-aks check-apiserver-connectivity --node jose \Error: getting vm: retrieving Azure resource ID of node jose from API server: nodes "jose" not found Node available in the config file will not use the API server: $ ./kubectl-aks check-apiserver-connectivity --node aks-nodepool1-17267820-vmss000002 |DEBUG[0000] Using VMSS information from config for node aks-nodepool1-17267820-vmss000002 Connectivity check: succeeded Without specifying any node, it will use aks-nodepool1-17267820-vmss000000 (current-node) from config: $ ./kubectl-aks check-apiserver-connectivity Connectivity check: succeeded Signed-off-by: Jose Blanquicet <josebl@microsoft.com>

This PR improves the management of node information in two situations:
Situation 1
Issue: When we set the default node using the
config use-nodecommand and we still want to run one command in a differente node (using--nodeor--id) without the need of changing the default node, the command will fail because we will have VMSS info + Node or VMSS info + ID and it will not know what to select.Solution: Don't read the current config vmss info if node or id was specified. It is not needed anyway.
Situation 2
kubectl-aksshould use the node information from config file when available:
