[NX-715] Component and asset query (rebased)

https://issues.sonatype.org/browse/NX-715

This PR is primarily about the query service in nexus-component-services. For the purpose of this PR, please ignore the state of nexus-component-assetstore and nexus-component-recordstore. They need to be cleaned up post-merge.
Can the given `componentId` be nullable? If yes then mark with @Nullable, if not then this needs a `checkNotNull`
