Lei Zhang updated SCB-2425:
---------------------------
Description:
The purpose of refactoring is to decouple distributed transaction implementation
*Alpha Module*
* Rename alpha-fsm to alpha-spec-saga-akka
* Add alpha-spec-saga-db
* Add alpha-spec-tcc-db
* Keep Acceptance module artifactId and directory name the same, e.g. rename
acceptance-pack-akka-spring to acceptance-pack-akka-spring-demo
* Rename persistence-jpa to alpha/alpha-persistence-jpa
*Alpha Using Spring SPI*
* Load AlphaSpecXXXAutoConfiguration through spring.factories under each module
* Configure the SPI module by parameters, likes alpha.spec.names=saga-db or
alpha.spec.names=saga-akka
*Alpha Configuration parameters*

*Omega Modules*
* Split OmegaSpringConfig into OmegaSagaSpringConfig and OmegaTccSpringConfig
*Omega AutoConfiguration*
* OmegaSagaSpringConfig using omega.spec.names=saga
* OmegaTccSpringConfig using omega.spec.names=tcc
* TransactionAspectConfig class of the omega-spring-tx module uses
ConditionalOnExpression to initialize beans
*Duplicate Code*
* Create class EclipseLinkJpaConfiguration in test case to avoid dependency on
class EclipseLinkJpaConfiguration in alpha-persistence-jpa module
* Because of the metrics API, each Spec module contains same classes as
follows(saga-xxx and tcc-xxx cannot be enabled at the same time)
