Table names are case-sensitive when querying

[jstirnaman]

Uppercase table names are allowed, but you must preserve the case when querying them:

"CPU" is needed to make table name in query to preserve the case.

+----------+
| count(*) |
+----------+
| 1        |
+----------+```
Without the `"`, you can see the same error

```❯ ./influxdb3 query -d test1 'select count(*) from CPU'
Query command failed: server responded with error [500 Internal Server Error]: query error: error while planning query: Error during planning: table 'public.iox.cpu' not found```
Note: I'm not on `3.7.0`, but I don't think version matters for this.

This is known, reason is stated below from Trevor (not tagging him as he is on PTO).

for case sensitive table names and column names (tags or fields) you need to use quotes in the query. This is due to the SQL parser implementation used in DataFusion adopting PostgreSQL semantics for case sensitivity.
