query namespace exists with GET Namespace

More efficient ns switches with kubens by querying only the namespace (instead of listing all namespaces). Signed-off-by: Ahmet Alp Balkan <ahmetb@google.com>

-### Examples
+# kubectx(1)
+
+kubectx is a utility to manage and switch between kubectl(1) contexts.
+
+```
+USAGE:
+  kubectx                   : list the contexts
+  kubectx <NAME>            : switch to context <NAME>
+  kubectx -                 : switch to the previous context
+  kubectx -c, --current     : show the current context name
+  kubectx <NEW_NAME>=<NAME> : rename context <NAME> to <NEW_NAME>
+  kubectx <NEW_NAME>=.      : rename current-context to <NEW_NAME>
+  kubectx -d <NAME>         : delete context <NAME> ('.' for current-context)
+                              (this command won't delete the user/cluster entry
+                              that is used by the context)
+  kubectx -u, --unset       : unset the current context
+```
+
+### Usage

 ```sh
-# switch to another cluster that's in kubeconfig
 $ kubectx minikube
 Switched to context "minikube".

-# switch back to previous cluster
 $ kubectx -
 Switched to context "oregon".

-# rename context
-$ kubectx dublin=gke_ahmetb_europe-west1-b_dublin
-Context "gke_ahmetb_europe-west1-b_dublin" renamed to "dublin".
+$ kubectx -
+Switched to context "minikube".

-# change the active namespace on kubectl
+$ kubectx dublin=gke_ahmetb_europe-west1-b_dublin
+Context "dublin" set.
+Aliased "gke_ahmetb_europe-west1-b_dublin" as "dublin".
+```
+
+`kubectx` supports <kbd>Tab</kbd> completion on bash/zsh/fish shells to help with
+long context names. You don't have to remember full context names anymore.
+
+-----
+
+# kubens(1)
+
+kubens is a utility to switch between Kubernetes namespaces.
+
+```
+USAGE:
+  kubens                    : list the namespaces
+  kubens <NAME>             : change the active namespace
+  kubens -                  : switch to the previous namespace
+  kubens -c, --current      : show the current namespace
+```
+
+
+### Usage
+
+```sh
 $ kubens kube-system
 Context "test" set.
 Active namespace is "kube-system".

-# go back to the previous namespace
 $ kubens -
 Context "test" set.
 Active namespace is "default".
-
-# change the active namespace even if it doesn't exist
-$ kubens not-found-namespace --force
-Context "test" set.
-Active namespace is "not-found-namespace".
---
-$ kubens not-found-namespace -f
-Context "test" set.
-Active namespace is "not-found-namespace".
 ```

-If you have [`fzf`](https://github.com/junegunn/fzf) installed, you can also
-**interactively** select a context or cluster, or fuzzy-search by typing a few
-characters. To learn more, read [interactive mode &rarr;](#interactive-mode)
-
-Both `kubectx` and `kubens` support <kbd>Tab</kbd> completion on bash/zsh/fish
-shells to help with long context names. You don't have to remember full context
-names anymore.
+`kubens` also supports <kbd>Tab</kbd> completion on bash/zsh/fish shells.

 ## Installation

-Stable versions of `kubectx` and `kubens` are small bash scripts that you
-can find in this repository.
+> **🥳📰 NEWS:** With v0.9.0 `kubectx` and `kubens` **are now rewritten in Go**.

+> [**Releases &rarr;**](https://github.com/ahmetb/kubectx/releases)

-Starting with v0.9.0, `kubectx` and `kubens` **are now rewritten in Go**.  They
-should work the same way (and we'll keep the bash-based implementations around)
-but the new features will be added to the new Go programs.  Please help us test

-The completion scripts have to be in a path that belongs to `$fpath`. Either
-link or copy them to an existing folder.
-
-Example with [`oh-my-zsh`](https://github.com/ohmyzsh/ohmyzsh):
+Available as official Arch Linux package. Install it via:

 ```bash
-mkdir -p ~/.oh-my-zsh/custom/completions
-chmod -R 755 ~/.oh-my-zsh/custom/completions
-ln -s /opt/kubectx/completion/_kubectx.zsh ~/.oh-my-zsh/custom/completions/_kubectx.zsh
-ln -s /opt/kubectx/completion/_kubens.zsh ~/.oh-my-zsh/custom/completions/_kubens.zsh
-echo "fpath=($ZSH/custom/completions $fpath)" >> ~/.zshrc
+sudo pacman -S kubectx
 ```

-If completion doesn't work, add `autoload -U compinit && compinit` to your
-`.zshrc` (similar to
-[`zsh-completions`](https://github.com/zsh-users/zsh-completions/blob/master/README.md#oh-my-zsh)).
+#### Debian

-If you are not using [`oh-my-zsh`](https://github.com/ohmyzsh/ohmyzsh), you
-could link to `/usr/share/zsh/functions/Completion` (might require sudo),
-depending on the `$fpath` of your zsh installation.
+Available as a Debian package for [Debian Buster (testing)](https://packages.debian.org/buster/kubectx), [Sid (unstable)](https://packages.debian.org/sid/kubectx) (_note: if you are unfamiliar with Debian release process and how to enable testing/unstable repos, check the [Debian Wiki](https://wiki.debian.org/DebianReleases)_):

-In case of errors, calling `compaudit` might help.
-
-#### Completion scripts for `bash`
-
-```bash
-git clone https://github.com/ahmetb/kubectx.git ~/.kubectx
-COMPDIR=$(pkg-config --variable=completionsdir bash-completion)
-ln -sf ~/.kubectx/completion/kubens.bash $COMPDIR/kubens
-ln -sf ~/.kubectx/completion/kubectx.bash $COMPDIR/kubectx
-cat << EOF >> ~/.bashrc
-
-
-#kubectx and kubens
-export PATH=~/.kubectx:\$PATH
-EOF
-```
-
-#### Completion scripts for `fish`
-
-```fish
-mkdir -p ~/.config/fish/completions
-ln -s /opt/kubectx/completion/kubectx.fish ~/.config/fish/completions/
-ln -s /opt/kubectx/completion/kubens.fish ~/.config/fish/completions/
