[#4851] fix: make TestHiveTableOperations setup independently (#4857)

### What changes were proposed in this pull request?

`TestHiveTableOperations` can be tested before `TestHiveTable`
initialized.
Make `TestHiveTableOperations::steup()` run alone.

### Why are the changes needed?

When we try to just run `gradle :catalogs:catalog-hive:test --tests
'org.apache.gravitino.catalog.hive.TestHiveTableOperations'`,
`TestHiveTableOperations` needs static variables which must be
initialized ahead, and it can't be run alone.

Fix: #4851 

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Refactor of unit test setup, local unit tests have passed.
