M6 Support for unit conversion and detection of compatible ports

[odeimaiz]

Ports of services can already be annotated with units and this information can be used to identify compatibility when pipelining services. This functionality must be extended to deal with equivalent units (e.g., mA/s and C/min^2) in order to ensure correct data conversion when passing it from service to service, as well as port compatibility assessment.

Deliverable: platform functionality (Q2)

@KZzizzle @odeimaiz PR ITISFoundation/osparc-simcore#2756 includes jsonschemas in ports which allows, among other constraints, range validation. For now, the validation takes places when node-ports is executed (i.e. prior to the actual service run) . In some cases this could be validated earlier even without running the pipeline. The latter is still not included.
