XD-1522: Allow only one label
XD-1365 Set ModuleDefinitions while deleteAll()

- When using AbstractDeployer.deleteAll(), the composed module definitions for the stream definition
is not set. Hence, the dependencies are not deleted from the ZK repository.
  - Fix `deleteAll()` to iteratively call delete(definitionName) which sets the ModuleDefinitions `beforeDelete`
- Remove calling `basicUndeploy()` at beforeDelete() in StreamDeployer
XD-1612 Simplify/Refactor UI controllers

- Remove unnecessary dependency injection when defining controllers
  - Inject only $scope as other dependencies are available from `xdAdmin.services`
- Create `XDCommon` service that returns the object representation for miscellaneous
methods such as logger, growl, timeout etc.
