[#5985] improvement(CLI): Fix role command that supports handling mul…

…tiple values (#5988)

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

In `GravitinoOptions`, the role option supports multiple values, but the
handleRoleCommand implementation currently only processes a single role
value. CLI should support create and delete multiple roles
simultaneously.


### Why are the changes needed?

Fix: #5985 

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

NO

### How was this patch tested?

local test + UT 

```bash
gcli role create -m demo_metalake --role role1 role2 role3
# role1, role2, role3 created

gcli role delete -m demo_metalake --role role1 role2 role3
# role1, role2, role3 deleted.

gcli role delete -m demo_metalake --role role1 role2 role3 unknown
# role1, role2, role3 deleted, but unknown is not deleted.

gcli role details -m demo_metalake
# Missing --role option.

gcli role details -m demo_metalake --role roleA roleB
# Exception in thread "main" java.lang.IllegalArgumentException: details requires only one role, but multiple are currently passed.
```
