Virtual ports should inherit the capabilities of their parent ports

[mathisrichter]

Objective of issue: Virtual ports should inherit the capabilities of their parent ports

Lava version:

• [ ] 0.4.0 (feature release)
• [ ] 0.3.1 (bug fixes)
• [x] 0.3.0 (current version)
• [ ] 0.2.0
• [ ] 0.1.2

I'm submitting a ...

• [ ] bug report
• [x] feature request
• [ ] documentation request

Current behavior:

• When a virtual port is created, it has a number of generic capabilities, like connecting. But when creating a virtual port on a RefPort, the user cannot use the connect_var() method on the virtual port.

Expected behavior:

• Whatever port a virtual port is created on, it should inherit all those capabilities that also make sense for the virtual port to have.

Steps to reproduce:

v = Var((6,))
rp = RefPort((1, 2, 3))
rp.reshape(newshape=(6,)).connect_var(v)  # this does not work
