Fix airshipctl config get-context maximum args

[SirishaGopigiri]

Bug Description
The airshipctl config get-context command currently doesn't limit on the number of arguments that can be passed. So when we pass more that one parameter(example as show below) it returns all the contexts.

airshipctl config get-context ephemeral-cluster target-cluster

Steps To Reproduce
Sample airship config file

apiVersion: airshipit.org/v1alpha1
managementConfiguration:
  dummy_management_config:
    type: redfish
    insecure: true
    useproxy: false
    systemActionRetries: 30
    systemRebootDelay: 30
contexts:
  test-cluster:
    contextKubeconf: ephemeral-cluster_ephemeral
    manifest: dummy_manifest
    managementConfiguration: dummy_management_config
  ephemeral-cluster:
    contextKubeconf: ephemeral-cluster_ephemeral
    manifest: dummy_manifest
    managementConfiguration: dummy_management_config
  target-cluster:
    contextKubeconf: target-cluster_target
    manifest: dummy_manifest
    managementConfiguration: dummy_management_config
currentContext: ephemeral-cluster
kind: Config
manifests:
  dummy_manifest:
    phaseRepositoryName: primary
    repositories:
      primary:
        checkout:
          branch: master
          force: false
          remoteRef: ""
          tag: ""
        url: https://review.opendev.org/airship/airshipctl
    metadataPath: manifests/site/test-site/metadata.yaml
    targetPath: xyz

For the above config file if we issue airshipctl config get-context ephemeral-cluster target-cluster it returns all the contexts. I think it would be better if we accept only one argument/parameter.

Expected behavior
Current output

managementConfiguration: dummy_management_config
manifest: dummy_manifest

managementConfiguration: dummy_management_config
manifest: dummy_manifest

managementConfiguration: dummy_management_config
manifest: dummy_manifest

Expected output:

accepts at most 1 arg(s), received 2

Simple fix would be to add Args: cobra.MaximumNArgs(1), in the cobra command
