When exposing the ports of a process one would expect that the receiving port namespace would not just inherit the ports but also the mutable properties of the PortNamespace, such as the default, valid_type, help, validator and required attribute. The method that was responsible for creating the new namespace and exposing the ports, ProcessSpec._expose_ports, failed to do this. However, plumpy already defined a method that did just this, PortNamespace.absorb(). To fix this problem, we decided to move the expose functionality to plumpy and leverage the absorb method, which already properly overloaded mutable properties of the donor namespace to the host namespace. The only other addition is that the implementation of exposing ports in plumpy did not yet have a memory, as required by the implementation in aiida-core. This implementation, along with the proper namespace property inheritance has now been released with plumpy v0.10.3, which is the new dependency. The expose methods in plumpy now also takes an optional dictionary namespace_options which can be used to override even the properties of the source namespace that would be inherited. If the ports are exposed into a namespace that does not yet exist in the target namespace, it will be constructed using this namespace_options dictionary as constructor keyword arguments. Note that these namespace options will *not* be used for any sub namespaces that will have to be created along the way, nor will they be used to override any of the properties of already existing sub namespaces.

Fixes #1634
Note: relies on fixes in
plumpythat have not yet been released.When exposing the ports of a process one would expect that the
receiving port namespace would not just inherit the ports but
also the mutable properties of the PortNamespace, such as the
default, valid_type, help, validator and required attribute.
Therefore the _expose_ports method is adapted to overload the
mutable properties from the source namespace to the target
namespace.
The method now also takes an optional dictionary namespace_options
which can be used to override even the properties of the source
namespace. If the ports are exposed into a namespace that does not
yet exist in the target namespace, it will be constructed using
this namespace_options dictionary as constructor keyword arguments.
Note that these namespace options will not be used for any sub
namespace that will have to be created along the way, nor will they
be used to override any of the properties of already existing sub
namespaces
