add transactional for deleteWorkerGroupById (#1119)

* move updateTaskState into try/catch block in case of exception

* fix NPE

* using conf.getInt instead of getString

* for AbstractZKClient, remove the log, for it will print the same log message in createZNodePath.
for AlertDao, correct the spelling.

* duplicate

* refactor getTaskWorkerGroupId

* add friendly log

* update hearbeat thread num = 1

* fix the bug when worker execute task using queue. and remove checking Tenant user anymore in TaskScheduleThread

* 1. move verifyTaskInstanceIsNull after taskInstance
2. keep verifyTenantIsNull/verifyTaskInstanceIsNull clean and readable

* fix the message

* delete before check to avoid KeeperException$NoNodeException

* fix the message

* check processInstance state before delete tenant

* check processInstance state before delete worker group

* refactor

* merge api constants into common constatns

* update the resource perm

* update the dataSource perm

* fix CheckUtils.checkUserParams method

* update AlertGroupService, extends from BaseService, remove duplicate methods

* refactor

* modify method name

* add hasProjectAndPerm method

* using checkProject instead of getResultStatus

* delete checkAuth method, using hasProjectAndPerm instead.

* correct spelling

* add transactional for deleteWorkerGroupById
