* Remove the server_id from session table, change it to worker_id on session_connection
This is step 1 in updating the worker table. The worker is becoming a public resource so it must have
a public id. We drop the server_id column on the session_connection table and add the worker_id column
so we can use the wt_public_key type. Since db migrations are applied while the controller is offline,
it should be safe to assume all session connections are not in a running state, thus allowing us to null
out all the worker ids in the session_connection table.
For now we don't have very good enforcement of the wt_public_id contraints, since the id is currently
defined in the worker config, but this will soon change and the worker's id will be generated by the
controller.
* Updating server_id references to controller_id.
* Adding worker tag db writing test.
* Move the server table back to the top.
* Update comment for the worker object.
* Update comment for the worker table.
* Update the newWorkerId call to take a context and fix its error.
* Correct comment for the wt_network_address domain.
* chore: Add new dbw dependency
* refactor: Convert to use dbw.DB
* refactor (db): Change GetTicket(...) signature
* feature (db tests): Added TestDeleteWhere(...)
Adding this allows us to eliminate a leak of the gorm library
* refactor: Add ctx to ScanRows(...) signature
This is required to refactor all the deprecated errors pkg calls.
This refactor required adding a context to quite a few call chains
and in particular the job scheduler bits
* feature (db/tests): Add support for test opt: WithTestLogLevel(...)
This test only option allows callers to specify a log level for the
underlying db package (where supported/applicable) when calling
TestSetup(...)
* refactor (db): Simplify Db type
Only store the underlying *DB and create the *RW on demand when
needed.
* refactor (oplog): Port to using dbw pkg for db operations
* refactor (db): Remove gormDB(...) func
* tests (db): Add unit tests for TestDeleteWhere(...)
* chore: make fmt changes to formatting
* Adds job repo
* Adds scheduler
* Adds plugin table which is a place holder for future expansion of the scheduler. Currently all jobs that are created are linked to the pi_system plugin which are jobs that are held in a local registeredJobs map populated at controller startup.
