Allow specifying name, namespace and order for the module

[dmgtn]

Problems:

1. We automatically camel-case module name, but if the module name has some abbreviation – we get ugly things, like getting nodeLocalDns, instead of 'nodeLocalDNS`.
2. Sometimes we need to know module namespace, but we don't have centralized mapping.
3. It would be generally better if we will pass namespace to helm install, at least:
   • we will have namespaces in helm list,
   • we will be able to use Release.Namespace, instead of hardcoding namespace name into each template.
4. Module order is part of ugly hardcode.

Proposal:

1. Add module.yaml to each module, and make it required. It should contain, at least, name (camel-cased), namespace and order, all required.
2. Use name (camel-cased) from module.yaml when generating helm values, and in all other places (list of enabled modules, logs, etc).
3. Add the automagic global variable with module-to-namespace mapping.

Extra logic:

1. When namespace of the module is changed – perhaps the module should be uninstalled first (as far I remember helm doesn't allow changing namespace for the installed release).
2. When module name changes, for addon-operator it should be similar to one module gone, and a new one added.
