File upload/manipulation through management API - modules, config files

It would be nice to have a possibility to upload certain files. Namely:

• create modules (e.g. JDBC drivers)
• copy .properties files - logging, security etc.
• ssh keys, certificates etc.

Could be limited to the examples above - i.e. one operation for creating/removing a module, another for copying a file to configuration/ .

/:add-config-file(file=foo.properties, ifExists=fail|skip|overwrite|...)

/:add-module(file=foo.jar, name=org.jboss.foo, version=main, dependencies=["org.jboss.bar"], imports=[...] exports=[...] ifExists=fail|skip|overwrite|...)

To avoid the complexity of distributing such file amongst managed domain, the op could be scoped to just a single host, like

/host=host1:add-config-file(...)

File transfer
=============

The same principle could be used as for deployments (-ModelNode.readExternal()- ?)

CLI's DeployHander#execute():

                OperationBuilder op = new OperationBuilder(request);
                op.addFileAsAttachment(f);
                request.get(Util.CONTENT).get(0).get(Util.INPUT_STREAM_INDEX).set(0);
                Operation operation = op.build();
                result = ctx.getModelControllerClient().execute(operation);
                operation.close();

Specifics
=========

The file manipulation in add-module would be performed by JBoss Modules through an appropriate API.

The file manipulation in add-config-file would be performed by the part of AS which knows where the config is actually read from (in case it is variable) - MSC?
