Make Worker handle installation of new packages

An example Scenario:

@requires_packages(package_a, package_b, package_c)
class CustomNode(cp.Node):
         _requires_pacakges: ClassVar[List[str]] = []


class WorkerPackageInstallationService:
     installer: installer
     sudocode: before_node_unpickle
     installer.install(nodes_metadata.required_pacakges)
     

The installation service should be installed on a worker, a agnostic wrapper that has the following:

1. Detect if conda environment
2. Detect if pip environment
3. installs packages
4. uninstalls packages

Per node installation might make more sense. Does adding them without using REST calls make more sense?
