Enable only deprecation warning for fnmatch deprecation

[yatin]

[1] enabled all types of warnings, as deprecation is added only DeprecationWarning should be enabled, without it it makes all sorts of warning visible, example:-
# openstack flavor list
/usr/lib/python3.9/site-packages/oslo_utils/fnmatch.py:25: DeprecationWarning: Using the oslo.utils's 'fnmatch' module is deprecated, please use the stdlib 'fnmatch' module.

  warnings.warn("The %s module is moved to barbicanclient/v1 "

sys:1: ResourceWarning: unclosed <socket.socket fd=4, family=AddressFamily.AF_INET6, type=SocketKind.SOCK_STREAM, proto=6, laddr=('::1', 35016, 0, 0), raddr=('::1', 8774, 0, 0)>
ResourceWarning: Enable tracemalloc to get the object allocation traceback

Should be fixed to enable only Deprecation warning so unnecessary warning's get's suppressed.
