Solution
As per Tendermint 0.16.0 , --p2p.seeds is now --p2p.persistent_peers. Update bigchaindb/tendermint container to use that configuration. Also disable --p2p.pex, we currently don't want the peer exchange.
Solution
Since BigchainDB and Tendermint are so tightly coupled we need to introduce a process supervisor to make them act like a single microservice, so that if BigchainDB crashes, Tendermint does as well and both are restarted and Tendermint requests a connection towards the proxy app.
In Kubernetes, they can be exposed as part of a one POD.
For BigchainDB as a system service/process, we need to introduce a process supervisor such as systemd.
This PR only solves the former.
Changes
Upgrade deployment from Tendermint v0.12.0 to v0.19.0
Update some documentation
Fix nginx-http entrypoint issues.
Update generate-configs.sh script to handle config generation without https-certificates.
Update Dockerfile to process dependency links introduced by abci
Integrate BigchainDB and Tendermint as a single microservice.
This required making BigchainDB to be exposed as a statefulset.
Introduce new liveness probe checks.

* Problem: No docs explaining use of MongoDB for querying
Solution: Start a new root docs page explaining how a node operator can use the full power of MongoDB's query engine, and can expose as much of that as they like to end users.
* Finished first draft of new docs page 'Querying BigchainDB'
