Return transactions for the user defined client access

[BMartinos]

Background:
A current limitation is noted where a non-admin users which is configured under a specific client, is able to see the transactions for all the clients thats assigned to the specific channel.

E.g:
Channel A - /fhir.*

Client A - System A
Client B - System BB
Client C - System CCC

User 1 - System A
User 2 - System BB
User 3 - System CCC

User 3 Logs into OpenHIM Console, and is able to view transactions for Channel A, but under all client (Client A, Client BB, Client CCC)

Expected outcomes:
If a user is linked to a specific client/role which is used to submit transactions to the OpenHIM, when the user views the transaction list, they should only be able to see the transactions which is linked to that specific users clients/roles. The OpenHIM core should interpret the users allowed clients/roles and filter out transactions which isnt assigned to the logged in user
