Better documentation about environment variables

[process0]

Took a minute to figure out i needed to specify HCLOUD_NETWORK in the Deployment environment variables. Are these variables socumented somewhere that I missed? Also would it make more sense to store all of them in a Secret along with the token?

const (
    hcloudTokenENVVar                        = "HCLOUD_TOKEN"
    hcloudEndpointENVVar                     = "HCLOUD_ENDPOINT"
    hcloudNetworkENVVar                      = "HCLOUD_NETWORK"
    hcloudDebugENVVar                        = "HCLOUD_DEBUG"
    hcloudLoadBalancersEnabledENVVar         = "HCLOUD_LOAD_BALANCERS_ENABLED"
    hcloudLoadBalancersLocation              = "HCLOUD_LOAD_BALANCERS_LOCATION"
    hcloudLoadBalancersNetworkZone           = "HCLOUD_LOAD_BALANCERS_NETWORK_ZONE"
    hcloudLoadBalancersDisablePrivateIngress = "HCLOUD_LOAD_BALANCERS_DISABLE_PRIVATE_INGRESS"
    hcloudLoadBalancersUsePrivateIP          = "HCLOUD_LOAD_BALANCERS_USE_PRIVATE_IP"
    nodeNameENVVar                           = "NODE_NAME"
    providerName                             = "hcloud"
    providerVersion                          = "v1.9.1"
)

Hey @process0,

when you use our deployment files those ENV variables are already in there. https://github.com/hetznercloud/hcloud-cloud-controller-manager/blob/master/deploy/ccm-networks.yaml.tmpl#L86 (Used when you follow our docs: https://github.com/hetznercloud/hcloud-cloud-controller-manager/blob/master/docs/deploy_with_networks.md)

But you are right, we will improve the documentation of our Environment variables here.
