Define Resql 2.1 DSL specifications

[turnerrainer]

AS AN Architect
I WANT Resql DSLs to follow a very strict, pre-defined structure
SO THAT I could create additional services based on them

AS A Developer
I WANT TO understand which requirements I have to fulfil when creating Resql DSLs
SO THAT I could get them correct right from the beginning

Acceptance Criteria

Schema declarations

• Have a separate section for schema declarations and an actual SQL
• Define allowed method types
• Define all required input parameters
• Link all input parameters with database schemas in use

SQL command

• Have a separate section for an actual SQL command
• Use : to define input parameters, e.g. :fname to represent POST parameter called fname (existing functionality)
• Do not apply any additional changes to the structure of SQL (existing functionality)

Publication

• Initial schema is published at https://github.com/buerokratt/Resql/blob/dev/docs/DSL/schema.md
• Confirmed schema is published at https://github.com/buerokratt/Resql/blob/main/docs/DSL/schema.md
