* jwa(back): Use gevent for gunicorn's workers
Since the backend only serves simple HTTP requests that need some K8s
data, instead of only have working processes we will also use greenlets.
This way we can have multiple user-space threads that will handle the
http requests.

* wa(front): Handle all-namespaces
The common library will add an event handler to dashboard's lib when it
is emitting all the namespaces. By extension, the common namespace
service will be exposing a new observable that will be emitting the list
of all the namespaces, when the user selects this from the dashboard.
This way current apps won't break, since they will simply not handle
this new observable.

The UIs will be showing a new column for the namespace only when the

Signed-off-by: Kimonas Sotirchos <kimwnasptd@arrikto.com>
* jwa(front): Make requests for all-namespaces
As a first iteration in order for the JWA to support showing Notebooks
from all namespaces it will be polling with batch requests. After all
the requests, for all the namespaces, succeed then the JWA will sort
them based on their name and show them in the table.
While this approach will be generating a significantly bigger amount of
requests, we chose this approach because:
1. It was simple to implement, since we only need to modify the frontend
2. We don't add any extra abstractions on the backend and keep the 1-1
relationship with the k8s api endpoints
3. To further optimize we now only look on K8s concepts and won't have
to adjust them to a custom backend implementation [2]

The notebook controller writes the last-activity annotation
before culling the Notebook, however, doesn't remove this
annotation before start. This causes the Notebook to be culled
again before is has a chance to start.
Fix:
* calculate correctly the podFound variable and ensure its value
its true only if the Pod is actually found. This way the culling
annotation will be removed when there is no Pod.

* build: Update components makefiles for building
We'll create a top-level Makefile under components/ dir
that has the following rules:
* build-all:
To build all images locally
* push-all:
* We can use a specific REGISTRY and retag the images
* Push all the images
This top-level Makefile will run the sub-Makefiles that every
component has for building and pushing the images.
We modified every sub-Makefile as follows:
* We don't use a registry in images by default
* Removed unused rules and vars
* Use the --dirty flag of git describe in TAG
--dirty[=<mark>]
Describe the working tree. It means describe HEAD and
appends <mark> (-dirty by default) if the working tree

* build: Create makefiles for notebook servers
The common starting point of building the notebook-server
images are the following 4 *base* images:
- base
- codeserver
- jupyter
- rstudio
All other server images need to build on top of them. We'll
dynamically pass the base images in every Dockerfile by
using an ARG IMG. We can set the value of this ARG during
docker build with the --build-arg CLI argument.
This way we build both the base images with a tag locally,
and then we pass that image as arg via the Makefile and build the rest
So we modified our building procedure as follows:
1. Build the base image since everything starts from there
2. Pass the base image as an ARG in the Dockerfiles of
jupyter, codeserver, rstudio images and build on top
3. Pass the base images in all other server images and build
on top
For that we will:
1. Create a Makefile for each of the notebook servers, in each folder
a. Each makefile will be responsible for building the bases and use args for passing them on
2. Use the central Makefile to call each Makefile from above
