425397f644 NGINX frontend for MongoDB and BigchainDB (#1304)
- Added NGINX deployment to frontend both BDB and MDB.
- Nginx is configured with a whitelist (which is read from a ConfigMap)
to allow only other MDB nodes in the closter to communicate with it.
- Azure LB apparently does not support proxy protocol and hence
whitelisting fails as nginx always observer the LB IP instead of the
real IP in the TCP stream.
- Whitelisting source IPs for MongoDB
- Removing deprecated folder
- Better log format
- Intuitive port number usage
- README and examples
- Addressed a typo in PYTHON_STYLE_GUIDE.md

7dbd374838 Running a single node on k8s (#1269)
* Single node as a StatefulSet in k8s
- uses bigchaindb/bigchaindb:0.9.1

* Updating README

* rdb, mdb as stateful services

* [WIP] bdb as a statefulset

* [WIP] bdb w/ rdb and bdb w/ mdb backends
- does not work as of now

* Split mdb & bdb into separate pods + enhancements
*  discovery of the mongodb service by the bdb pod by using dns name.
*  using separate storage classes to map 2 different volumes exposed by the
mongo docker container; one for /data/db (dbPath) and the other for
 /data/configdb (configDB).
*  using the `persistentVolumeReclaimPolicy: Retain` in k8s pvc. However,
this seems to be unsupported in Azure and the disks still show a reclaim
policy of `delete`.
*  mongodb container runs the `mongod` process as user `mongodb` and group
`mongodb. The corresponding `uid` and `gid` for the `mongod` process is 999
and 999 respectively. When the constinaer runs on a host with a mounted disk,
the writes fail, when there is no user with uid 999. To avoid this, I use the
docker provided feature of --cap-add=FOWNER in k8s. This bypasses the uid and
gid permission checks during writes and allows writes.

* Delete redundant k8s files, add cluster deletion steps.
