As a developer, I'd like to be able to depend on a shared library that configures subscriptions/products for subscription watch services.

Note: we should use compileOnly as the dependency scope for quarkus platform in order to not force a specific version of snakeyaml onto spring boot services.

Done:

• Library created within rhsm-subscriptions repo (gradle submodule) which depends on snakeyaml
• Library name should be swatch-product-configuration - on the same level as swatch-core (can reference build.gradle structure of clients and/or swatch-core)
• Dependency added to swatch-core
• Dependency added to swatch-producer-aws
• Library doesn't do anything at this point
