class around QuartzScheduler - FlowTriggerScheduler.
The class provides
schedule all flows in a project with flow trigger defined with quarz scheduler.
unscheduleAll all flows in a project with flow trigger defined with quartz scheduler.
Retrieve the list of current flow schedules from quartz database.
FlowTriggerScheduler will be used to schedule/unschedule flows if schedule is part of flow configuration file(flow 2.0) when project is uploaded/deleted.
Also when flow trigger is defined, thus schedule is part of flow config, scheduling those flows from UI/API is disallowed.
Tested via manual uploading a project with flow trigger but unit test of this part is a bit tricky, will add unit test if possible or verify in integration test.

(#1632)
The motivation of moving dependency plugin interface code(#1609, #1610) out from azkaban web server module to a new module is to expose minimum set of code to external dependency plugin avoiding unnecessary introduction of other classes in the development of dependency plugin. If those interface sit in the azkaban web server module, dependency plugin developers will have to depend on jar of that module containing a lot of other classes more than needed. This might potentially cause dependency conflict.
This PR also includes bettering renaming on test dependency type and consolidating different test dependency types into one package.

PR injects flow trigger service(#1627) into azkaban web server. Flow trigger service will start if enabled in the config file. Upon start, flow trigger service initializes all dependency plugins and recover running trigger instance from last run status.

section in flow yaml file (#1630)
The following validation steps are performed against flow trigger when parsing flow yaml file:
if specified max wait min must >= 1, if not, allowed max wait min(10 days) is applied.
flow trigger schedule cannot be null
flow trigger schedule type must be cron
flow trigger schedule value must be a valid cron expression
flow trigger schedule section contains type and value only
dependency name must be unique at flow trigger level
dependency config(type + params) must be unique at flow trigger level.
if max wait min >= allowed max wait min, it will be automatically set to allowed one(10 days)
dependency name/type are required.

mainly a refactor, in order to fix JDBC intermittent test failure reported in #1614. Looks like JdbcTriggerImplTest uses a deprecated class to construct h2 test db. The fix is to replace it with the one which all XXXDaoTest currently are depending on.
Tested by ./gradlew :azkaban-common:test

a singleton class in the AZ web server to process all flow trigger-related operations. Externally it provides following operations -
Create a trigger instance based on trigger definition.
Cancel a trigger instance.
Query running and historic trigger instances.
Recover incomplete trigger instances.
Internally, it
maintains the list of running trigger instance in memory.
updates status, starttime/endtime of trigger instance.
persists trigger instance to DB.
FlowTriggerService will be leveraged by Quartz scheduler, our new AZ scheduler to schedule starting triggers.
Flow Trigger Service internally contains a single-threaded executor service to process all trigger instance related operation to avoid complicated cases of race condition.
