    Modified client class related queries

src/hooks/dhcp/pgsql_cb/tests/pgsql_cb_dhcp4_unittest.cc
    TEST_F(PgSqlConfigBackendDHCPv4Test, setAndGetAllClientClasses4Test)
    TEST_F(PgSqlConfigBackendDHCPv4Test, getClientClass4Test)
    TEST_F(PgSqlConfigBackendDHCPv4Test, createUpdateClientClass4OptionsTest)
    TEST_F(PgSqlConfigBackendDHCPv4Test, getModifiedClientClasses4Test)
    TEST_F(PgSqlConfigBackendDHCPv4Test, deleteClientClass4Test)
    TEST_F(PgSqlConfigBackendDHCPv4Test, deleteAllClientClasses4Test)
    TEST_F(PgSqlConfigBackendDHCPv4Test, clientClassDependencies4Test)
    TEST_F(PgSqlConfigBackendDHCPv4Test, multipleAuditEntriesTest)
    - new tests

src/lib/pgsql/pgsql_connection.h
    Updated schema version to 10.0

src/share/database/scripts/pgsql/Makefile.am
    Added upgrade_009_to_010.sh

src/share/database/scripts/pgsql/dhcpdb_create.pgsql
    Schema updated to 10.0:
    Replace setClientClass<4/6>Order()
    - wrong local variable type, replace int constants with
    boolean constants

    dhcp<4/6>_client_class_dependency tables -
    - primary key needs to be composite to allow muliptle rows per class id

    func_dhcp<4/6>_client_class_check_dependency_BINS() - trigger functions
    need to return NEW not NULL
