MIABIS Core v 3.1 update

[niinae]

• [Component] status attribute: The status attribute in connection component with description "The state of the Collection functions" and values Active, Ended and Other can be confusing in this context. The current definition leaves room for misinterpretation. Does this mean the collection of new samples and data from donors is active or ended? Collections are usually constantly updated with new data derived from samples, so they can be ‘active’, while no new samples are collected.
• Need to synchronise with "Dataset type" and "Services" when they are completed
• Update Sample type attribute to synchronise with Sample v1.1 update:
  ** merge sample type and detailed sample type as one attribute.

• Networks that declare a focus on a specific disease should also be able to specify that disease. The use case would be for instance the COVID-19 network. This would make it very easy for us to classify collections / biobanks that are part of the network for the right disease category.
