What changes were proposed in this pull request?
This PR proposes to use V2 commands as default as outlined in SPARK-36588, and this PR migrates
ALTER NAMESPACE ... SET LOCATIONto use v2 command by default.Note that the work to make v1/v2 commands consistent was done in #34686 and tests covering both v1/v2 were done in #34610.
Why are the changes needed?
It's been a while since we introduced the v2 commands, and it seems reasonable to use v2 commands by default even for the session catalog, with a legacy config to fall back to the v1 commands.
Does this PR introduce any user-facing change?
No
How was this patch tested?
Existing *AlterNamespaceSetLocationSuite tests cover this PR's change.
