command

Make it less prone to random websocket errors.

For unknown reason browsers sometimes close websockets with an invalid

close code, for example 15393. It prevents from running @OnClose methods

in LAMS websocket servers. Since we do not have control over this

situation, it is better to skip CloseReason parameter all together.

Synchronous approach would work only on LAMS installation with a single

application server. For multi-server environment we need to wait for the

proper server to pick up the command from DB.

They did not lead to fixing the problem and were actually unnecessary:

FileDAO does not use DB connections, so no need for transactions.

Some classes in content repository were using DAO methods directly,

without enveloping them in a transaction. Now they all go through

RepositoryService.

These methods need to start with "dao" prefix so they are not picked up

by CheckCredentialTicketBeforeAdvice.

An exception can occur also when session gets open, not only when it

gets closed.

MonitorService interfaces are redefined now:

1. IMonitorService is going to be used by core modules.

2. IMonitorFullService is used inside of lams_monitoring only and

nowhere else, as it contains lams_monitoring's internal logic and

classes.

LearnerService interfaces are redefined now:

1. ILearnerService is used by core modules. Also tools no longer

use it.

2. ILearnerFullService is used inside of lams_learning only and

nowhere else, as it contains lams_learning's internal logic and

classes.

3. ICoreLearnerService is removed, its method are split between

ILearnerService and ILearnerFullService.

Tools and core start using shared learning classes that were

recently moved from lams_learning to lams_common.

Remove any leftover dependencies on lams_learning.
