changed cloud log file to accept periods and colons

[kylershih0614]

Description

Changed file pattern when looking for cloud log files to allow a colon or a period as part of the file pattern. Windows does not allow for colons in the filename therefore this allows us to checkout the repo on a windows machine.

Renamed the files tests/artifacts/xdmod/referencedata/nutsetters/2019-06-26T00:00:00_2019-06-26T23:59:59.json
and tests/artifacts/xdmod/referencedata/openstack/2018-04-17T00:00:00_2018-04-30T23:59:59.json to tests/artifacts/xdmod/referencedata/nutsetters/2019-06-26T00.00.00_2019-06-26T23.59.59.json and tests/artifacts/xdmod/referencedata/openstack/2018-04-17T00.00.00_2018-04-30T23.59.59.json

edited configuration/etl/etl.d/jobs_cloud_openstack.json to accept both colons and periods as a valid file format.

Tests performed

I used the tests in Docker and ran the integration, component, and regression tests.
