* refactor: expose parsed api short name and version as fields in Service (#1075)

* Exposes parsed apiShortName and apiVersion as fields in Service.java, since the source fields (defaultHost and protoPakkage) are both defined per-service. 

* Adds these two fields correspondingly to GapicClass so that it can be composed from Service given these two upstream fields, then replaces withDefaultHost (for building GapicClass) withApiShortName and withApiVersion. (Composers and tests where this is currently used for sample generation are updated)

* This change will enable Spring Codegen (when eventually split out from this repo) to reuse this parsing logic in descriptive comments and metadata. It also moves the parsing logic to earlier in the parse-compose process.

* fix: fix REST transport client creation generated javadoc sample (#1077)

* fix: fixes regionTag breakage

* remove errant comment
