changes made to bcfdd6dbaf.

* generate RPC docs using Slate (#691)

* update changelog

* skip if branch not develop

* slate: only build if rpc/core has changes

* fetch develop to compare against

* slate: build on master only

* [rpc/core] use original repo, not fork in README

in order to avoid having to stop it manually

Fixes https://github.com/tendermint/tendermint/issues/1162

Databases as a service!

Can now access Databases as a remote service
via gRPC for performance and easy deployment.

The caveat is that each service is stateful in regards to
the DB i.e. each unique service uses only one unique DB
but nonetheless multiple clients can access it.

A full standalone example

```go
package main

import (
  "bytes"
  "context"
  "log"

  grpcdb "github.com/tendermint/tmlibs/grpcdb"
  protodb "github.com/tendermint/tmlibs/proto"
)

func main() {
  addr := ":8998"
  go func() {
    if err := grpcdb.BindRemoteDBServer(addr); err != nil {
      log.Fatalf("BindRemoteDBServer: %v", err)
    }
  }()

  client, err := grpcdb.NewClient(addr, false)
  if err != nil {
    log.Fatalf("Failed to create grpcDB client: %v", err)
  }

  ctx := context.Background()
  // 1. Initialize the DB
  in := &protodb.Init{
    Type: "leveldb",
    Name: "grpc-uno-test",
    Dir:  ".",
  }
  if _, err := client.Init(ctx, in); err != nil {
    log.Fatalf("Init error: %v", err)
  }

  // 2. Now it can be used!
  query1 := &protodb.Entity{Key: []byte("Project"), Value:
[]byte("Tmlibs-on-gRPC")}
  if _, err := client.SetSync(ctx, query1); err != nil {
    log.Fatalf("SetSync err: %v", err)
  }

  query2 := &protodb.Entity{Key: []byte("Project")}
  read, err := client.Get(ctx, query2)
  if err != nil {
    log.Fatalf("Get err: %v", err)
  }
  if g, w := read.Value, []byte("Tmlibs-on-gRPC"); !bytes.Equal(g, w) {
    log.Fatalf("got= (%q ==> % X)\nwant=(%q ==> % X)", g, g, w, w)
  }
}
```

- Updated Dockerfile and created build-docker target
- Changed localnode docker image to set permissions to more permissive (docker has different user than host system)
- Added sentry node terraform and ansible script

* Added new Makefile targets for local testnet running using docker

* Added localnode docker image description, some documentation and refactored to use the tendermint testnet command

* Fixes for the new tendermint testnet command

* More fixes on tendermint testnet and docker-compose

* Changed logging

* Added missing targets to phony

Reasons:
1) all deps we're using should be passing tests (including external)
2) deps can require complicated setup for testing
3) the person responsible for releasing Tendermint should be cautious
when updating a dep

bad dev experience

* de-mystify tests & run them in parallel (#1031)

* test optimization for jenkins (#1093)

* makefile cleanup

* tests: split fast and slow go tests, closes #1055

* pr comments

* restore circle conditions

* fix need_abci

* ...

* docker run: no :Z for circle?

* Remove cmd breaking comment

To achieve faster feedback cycles for our feature PRs this change
reduces the average buildtime from 35 to ~6min by utilising their new
2.0 offering based on docker and nomad. We make use of parallel build
steps wherever possible so that the duration is determined by the
slowest test suite (p2p).

This is an intermediate step until we move our CI/CD completely
on-premise for more control and added security.

* Switch to dep from glide for dependency management

* Update CI dockerfile to use dep instead of glide

* Wrong file extension

* Run 'dep ensure' after copying code

* Install glide to handle abci dependencies in testing

* Use `dep ensure -vendor-only` to setup vendor directory before installing source code on ci

get rid of gox

build target builds inside docker, dev-build - locally

Revert "build target builds inside docker, dev-build - locally"

This reverts commit 8ba89d5e8c.

add build tags to make build/build_race/install

use tendermint's fork of glide instead of tar.gz

remove TMHOME unused var + set length for git hash

get rid of GOTOOLS_CHECK

fixes after review

zip

needed for distribution

Should fix a nondeterministic bug so...
