slugging, make the namespace fetching optional.

- `theme_display_vagrant`. This feature is disabled by default, use `yes` to display Vagrant status in your prompt. Please note that only the VirtualBox and VMWare providers are supported.
- `theme_display_vi`. By default the vi mode indicator will be shown if vi or hybrid key bindings are enabled. Use `no` to hide the indicator, or `yes` to show the indicator.
- `theme_display_k8s_context`. This feature is disabled by default. Use `yes` to show the current kubernetes context (`> kubectl config current-context`).
- `theme_display_k8s_namespace`. This feature is disabled by default. Use `yes` to show the current kubernetes namespace.
- `theme_display_user`. If set to `yes`, display username always, if set to `ssh`, only when an SSH-Session is detected, if set to no, never.
- `theme_display_hostname`. Same behaviour as `theme_display_user`.
- `theme_show_exit_status`. Set this option to `yes` to have the prompt show the last exit code if it was non_zero instead of just the exclamation mark.
