refactor the makefile

[arschles]

it's gotten very large, and is responsible for a few different tasks:

1. building the project, dockerizing, deploying to k8s
   • requires a second target to build the minio binary from master on https://github.com/minio/minio. that target may go away when the minio server becomes stable
2. building the mc binary from master on https://github.com/minio/mc, dockerizing a second image and deploying that to k8s. The build step may go away when the mc client becomes stable
3. build the mc integration tests, dockerizing a third image, and deploying that to k8s

It may make sense to split the integration tests in (3) into a separate repository. Regardless, the makefile is hard to follow.

Targets should be grouped together, and have a comment for each group, and each target should also be commented.

Also, an overview of the high level targets and workflows should be on the README.

Finally, dependencies don't make a ton of sense right now. Some ideas:

• docker-push could depend on docker-build but it isn't now
• does it make sense for docker-build to depend on build-server and build at once?
