Repository: jaegertracing/jaeger

Issue:
Relocate docker/ folder from root of the project
### Requirement

We would like to have less clutter in the root of the repository

### Problem

The `docker/` directory contains just two docker files that are used during CI to build images

### Proposal

* Move `docker` dir under `scripts/build`
* Update all references in the repository to match the new location

```sh
$ rg 'docker/(base|debug)'
Makefile
34:				   -not -path './docker/debug/*' \

scripts/makefiles/Docker.mk
16:		docker/base
23:		docker/debug
30:		docker/base

scripts/lint/check-go-version.sh
97:check docker/debug/Dockerfile "^.*golang:$version_regex" "$go_latest_version"
```
