What changed?
Refactored these 5 functions to be an interface PersistenceManagerFactory:

• initializeExecutionStore(c *cli.Context, shardID int) (persistence.ExecutionManager, error)
• initializeHistoryManager(c *cli.Context) (persistence.HistoryManager, error)
• initializeShardManager(c *cli.Context) (persistence.ShardManager, error)
• initializeDomainManager(c *cli.Context) (persistence.DomainManager, error)
• initPersistenceFactory(c *cli.Context) (client.Factory, error)

and add it to deps struct
Also add a mock file for persistenceManagerFactory

Why?
For a better testability
