Runs the given state through the pipeline. It has to be a map of:

• :query: the GraphQL query string,
• :operation-name: the GraphQL operation to run (if multiple are given),
• :variables: a map of variable names and values,
• :context: a map describing the context of the operation (e.g. session information).

This returns an execution result consisting of the input state, plus:

• :status: either :success, :exception or :error.
• :data: the execution result data (if available),
• :exception: a potentially thrown exception,
• :error: a keyword describing the kind of error encountered,
• :errors: a map describing the encountered errors.

opts has to be a map of alumbra.spec-compliant components:

• :parser-fn
• :validator-fn
• :canonicalize-fn
• :executor-fn

Like run but uses the given Ring request to extract :query, :operation-name and :variables.

Additionally, opts may contain a :context-fn key that will be applied to the request to derive the :context key.

Note that the request’s :body has to be a map (i.e. already JSON-decoded).
