Introduce createGoals on SDM

[cdupuis]

This PR adds support to use createGoals function on the SDM instance inside configure:

export interface SpringGoals extends AllGoals {
    autofix: Autofix;
    version: Version;
    codeInspection: AutoCodeInspection;
    pushImpact: PushImpact;
    build: Build;
    dockerBuild: DockerBuild;
}

export const configuration = configure<SpringGoals>(async sdm => {

    const goals = await sdm.createGoals(SpringGoalCreator, SpringGoalConfigurer);

    return {
        check: {
            test: IsMaven,
            goals: [
                [goals.cancel, goals.autofix],
                [goals.codeInspection, goals.version, goals.fingerprint, goals.pushImpact],
            ],
        },
    ...
    };
});

This is entirely optional to use and backwards compatible.

Removing auto-merge labels for now as I want to make some minor tweaks.

Looks good. No hard suggestions, just things to consider.
