Add Satus for DrugAdministrationEvent for the FHIR IPS profile MedicationSattement

[KateSerafimova]

The MedicationStatement profile is expected to have a status, one of the following: active | completed | entered-in-error | intended | stopped | on-hold | unknown | not-taken

There is already an action status in use - for Procedure. It will have to be mapped for some of the values, and "intended" is missing and I will add the SNOMED code 385661002 | Considered and not done (qualifier value) | for it, based on my exploration. The other mappings to SNOMED regarding the action status are provided in the annotation guideline, as the table bellow.

As default will be selected "active", meaning in-progress.

actionStatus	MedicaitonStatement status	SNOMED code
in-progress	active	385651009 |In progress (qualifier value)|
not-done	not-taken	385660001 |Not done (qualifier value)|
on-hold	on-hold	385655000 |Suspended (qualifier value)|
completed	completed	410513005 |In the past (qualifier value)|
entered-in-error	entered-in-error	723510000 |Entered in error (qualifier value)|
stopped	stopped	410545000 |Stopped before completion (qualifier value)|
unknown	unknown	410537005 |Action status unknown (qualifier value)|

There is a bug in the implementation - the property hasStatusCode needs to be restricted as Subclass of, not as Equivalent class.
