Support Java Modules

[aalmiray]

v2.4.4 defines an automatic module name

$ jarviz module name --gav com.networknt:json-schema-validator:1.0.8
subject: json-schema-validator-1.0.8.jar
name: json.schema.validator
source: filename
automatic: true
valid: true

$ jarviz module descriptor --gav com.networknt:json-schema-validator:1.0.8
subject: json-schema-validator-1.0.8.jar
name: json.schema.validator
version: 1.0.8
open: false
automatic: true
requires:
  java.base mandated
contains:
  com.networknt.schema
  com.networknt.schema.url

$ jarviz bytecode show --gav com.networknt:json-schema-validator:1.0.8
subject: json-schema-validator-1.0.8.jar
Unversioned classes. Bytecode version: 50 (Java 6) total: 72

I'd be great if the library supplied a full Java module descriptor. It's possible to keep bytecode baseline compatible with Java 8 while providing a full module descriptor thanks to ModiTect. This will help modular projects that consume this library, specifically those that create custom Java Runtimes with jlink, as the latter does not support automatic modules but explicit modules. If interested I can send a PR to make it happen.

Depends on ethlo/itu#14

@aalmiray I am open to adding module support for the current Java 8 release package. FYI, @fdutton and I have discussed having two branches once we finish the validator implementations.

@stevehu Thanks! I did notice #562 before submitting this issue. Figured it was best to ask 😅
Would you accept a PR configuring ModiTect to solve this feature?

[stevehu]

Yes. Let's do that before we have the two branches. Thanks a lot for your help.
