This commit introduces validation logic to `ark restore logs`
command, the way it already exists in other commands like `ark
restore create`.
Before the logs for a restore are fetched from the server, the
server is contacted to check if the specified restore exists. If
it does not, it errors out.
Fixes#389

Add the ability for the Ark server to run in any namespace.
Add `ark client config get/set` for manipulating the new client
configuration file in $HOME/.config/ark/config.json. This holds client
defaults, such as the Ark server's namespace (to avoid having to specify
the --namespace flag all the time).
Add a --namespace flag to all client commands.
