[COST-5565] - Fix bug in old tag matching logic

[lcouzens]

Jira Ticket

COST-5565

Description

This change will remove the line to lower tag key/values in the cloud dataframe before trying to match them with OCP tags. Tag matching is case sensitive and setting tags to lower inadvertently prevents us matching.

Testing

1. Checkout Branch
2. Restart Koku
3. Load ocp on cloud data with tag matching data (make sure to use upper case tags)
4. See data is matched by tag correctly

Checkout main and do the same:
see that we fail to match on tags because app != APP

Note:
This was found while investigating differences in cost from the new managed tables flow. Cost didnt match because the old flow was not correlating tag costs as expected.
