Schema snippets

[garrytrinder]

From @waldekmastykarz

if you start from the snippet, you have it already, but if you have a file already, it's a PITA to figure out the schema URL

Let's create the following snippets for each schema URL

Prefix	URL
devproxy-plugin-crudapi-schema	https://raw.githubusercontent.com/microsoft/dev-proxy/main/schemas/v1.0/crudapiplugin.schema.json
devproxy-plugin-genericrandomerror-schema	https://raw.githubusercontent.com/microsoft/dev-proxy/main/schemas/v1.0/genericrandomerrorplugin.schema.json
devproxy-plugin-mockresponse-schema	https://raw.githubusercontent.com/microsoft/dev-proxy/main/schemas/v1.0/mockresponseplugin.schema.json
devproxy-plugin-ratelimiting-schema	https://raw.githubusercontent.com/microsoft/dev-proxy/main/schemas/v1.0/ratelimitingplugin.schema.json
devproxy-config-schema	https://raw.githubusercontent.com/microsoft/dev-proxy/main/schemas/v1.0/rc.schema.json

When implementing the devproxy-plugin-crudapi-schema snippet, I noticed that we get an error saying that $schema is not allowed.

This isn't the case when using the devproxy-config snippet however.

The difference between the two schemas is that rc.schema.json has additionalProperties set to true on the root, whereas crudapiplugin.schema.json has additionalProperties set to false on the root, so explains why the warning appears as it is not defined in the schema.
