kube-config: add custom client configuration injection

[FlorianJDF]

What type of PR is this?

/kind feature

What this PR does / why we need it:

Makes possible to provide a client.configuration object to the function that creates new client api.
This allow to provide the same configuration when calling config.load_kube_config()and config.new_client_from_config_dict(kubeconfig)

Right now, the function new_client_from_config_dict automatically creates a new Configuration object

Which issue(s) this PR fixes:

Fixes #1967

Does this PR introduce a user-facing change?

Added: "client.configuration" object as input of function "config.new_client_from_config_dict()"

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

with this PR, how would you set the proxy to resolve #1967?

my_client.configuration.proxy = "MY_HTTP_PROXY"
client.CoreV1Api(api_client=my_client).list_namespace()

[FlorianJDF]

This allowed me to have my client working perfectly behind a proxy:

my_client_configuration = client.Configuration
my_client_configuration.proxy = os.getenv("HTTP_PROXY", None)
k8s_cluster_client = config.new_client_from_config(config_file=my_config_file, client_configuration=my_client_configuration)

With this solution, you need to find the env vars yourself.
But in a second time I could improve this to find those env vars automatically.
