[Tests] IT tests and test utils update to fix failing tests for serverless

[manasvinibs]

Description

Some of the IT tests are failing in serverless even though data exist and functionality working as expected. RCA for such failures are sharding differences between data sources Leading to different ranking and different order in the schema fields in the response.

1. So instead of hardcoding the expected schema order in the assertions, in this change I'm dynamically checking the schema names with its values during assertion to make sure if schema order is different in the responses due to different sharding difference, we are still able to check the correctness of the tests.
2. Sorting the data rows before assertion to make sure different data sources can have data in any order if sort is not applied and still have the correct data init.

not quite sure about this..
is the data rows for dedup test case not being sorted causing failure in IT? because this seems like actual coding logic for dedup, instead of providing pre-validated expected value (like the original verifyDataRows(result, rows(true), rows(false), rows(true), rows(false))

[manasvinibs]

No the failure was not because of the sorted value but the size of the data rows in the responses. Here we were hardcoding the expected response to be of size 4 but different data sources having different number of rows even though are de-duplicated, due to this hard coded check tests would fail. So instead of hard coding assertions, we can check the deduplication of the rows based on the response data.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/sql/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/sql/backport-2.x
# Create a new branch
git switch --create backport/backport-2902-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 6972487e855599745df909292d699d37f82282c7
# Push it to GitHub
git push --set-upstream origin backport/backport-2902-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/sql/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-2902-to-2.x.
