Rename all assemble and deploy rules: maven_assembly; npm_deployment, etc.

[alexjpwalker]

The top-level packages are named npm, pip, maven etc. while the rule names begin with assemble and deploy - there is a misalignment here.

[alexjpwalker]

npm, pip etc. are clearly stronger domains than assemble and deploy. This gives us maven_assemble.

Now, assemble and deploy are verbs, which does not really fit the paradigms of a declarative language like Bazel.

So the refactor we're leaning towards is:

• assemble_maven => maven_assembly
• deploy_maven => maven_deployment
• assemble_pip => pip_assembly
• deploy_npm => npm_deployment

(and so on and so forth.)

Let's make this change once we condense the GitHub repos, so that it's easier to propagate. cc @haikalpribadi .

Indeed, let's rename them, but after we collapse the repositories.
