[Edge device templates] - Define module commands request/response model

[kbeaugrand]

The primitive types we should be able to take in account:

• boolean
• date
• datetime
• double
• duration
• float
• integer
• long
• string
• time

Here is a documentation of how Azure Digital twins defines types primitives: https://github.com/Azure/opendigitaltwins-dtdl/blob/master/DTDL/v2/dtdlv2.md#primitive-schemas

In addition, we should be able to define complex types:

• enum
• object

Here is a documentation of how Azure Digitial twins defines the complex types: https://github.com/Azure/opendigitaltwins-dtdl/blob/master/DTDL/v2/dtdlv2.md#complex-schemas

The object should be defined and is able to handle all of the types above.

Please see here how Azure Digital twins defines the objects: https://github.com/Azure/opendigitaltwins-dtdl/blob/master/DTDL/v2/dtdlv2.md#object

In addition, please see an exemple of how we can define a command request payload in a UI :
