Re: [sdw] Should Observer and Host classes be equivalent to or superclass of Sensor and Platform? (#1408)

related to #1413, we need to decide if these are moved into SOSA, or remain in SSN

In addition, I think we should also discuss `Deployment `here, as tightly linked to `Observer` and `Host`. 

Based on the definition of `System `as "a unit of abstraction for pieces of infrastructure that implement [Procedures](https://www.w3.org/TR/vocab-ssn/#SOSAProcedure)", I fail to see the rational for having `Sensor ` as a sub-class of System but not the more abstract `Observer `(even a human `Observer `follows a `Procedure`)

`Platform `isn't a `System `anyway, only `hosts` `Systems`.

`Deployment `is in SSN, would need to be shifted to SOSA
