[oracle] Fix used bytes logic

[niraj-elastic]

Description

The field oracle.tablespace.space.used.bytes is calculated wrongly

Currently we are showing total bytes of tablespace in integration which seems to be incorrect for the field description. This PR will update this query to do following calculation space.used.bytes = Total bytes - Free Bytes

Also fixed visualization related to total.bytes

In visualization "Table space total size" There are two defrent queries are used for counting total bytes.
For NON-TEMP we are showing used+free which is correct.

But for TEPM we are directly showing total bytes. which is incorrect and shows total of all the tablespace.

@niraj-elastic Can you share the before and after of the dashboard? Are there changes other than label change in dashboard?

[ishleenk17]

More details on this, please.
How is this validation removal being handled in the PR?

[niraj-elastic]

Since the datastream.dataset filter is already added to oracle. we don't need to exclude this check. So we can remove this check file.
