Problem Statement

• Dir Conf store is not in sync when used from different threads.

Design

Added DirKvPayload class in kvstore for Dir Conf store operations.
tested PR with Dir conf store as below and for different threads , data is in sync now:
`>>> from cortx.utils.conf_store import Conf

Conf.load('m1', "dir:///tmp/cortx")
Conf.load('m2', "dir:///tmp/cortx")
Conf.set('m1', 'key1', 'val1')
Conf.save('m1')
Conf.get('m1', 'key1')
'val1'
Conf.get_keys('m1')
['key1']
Conf.get_keys('m2')
['key1']
`

Ran tests:
`[root@ssc-vm-g4-rhev4-1881 conf_store]# ./test_conf_store_dir.py
dir:///tmp/tmptt5e3u1x
....

Ran 4 tests in 0.143s

OK
