Develop a new transaction channel for the CR to SHR reconciliation process

[rcrichton]

For this work we need a new channel that is able to poll the CR for identifier updates and update the SHR when these changes happen. A more detailed description of this process can be found here: https://jembiprojects.jira.com/wiki/download/attachments/8913025/130618%20%28SK%20WN%20RC%29%20Patient%20Merge%20Restore%20Document.pdf?version=1&modificationDate=1371729437421&api=v2

A design of how this channel should work can be found at: https://docs.google.com/a/jembi.org/document/d/1gearD1fD-aJBbh6rWXhnc9HCkPwprIyxKV6vriWtWWg/edit#heading=h.gw3xkfwyg6ji
