Added the api to delete config key
Fixes #3488

How did you test it?

• Create a config.

--header 'Content-Type: application/json' \
--header 'api-key: test_admin' \
--data '{
    "key":"keke",
    "value": "keke"
}'

• Delete the config

curl --location --request DELETE 'http://localhost:8080/configs/keke' \
--header 'Content-Type: application/json' \
--header 'api-key: test_admin'

• Get the config

curl --location --request GET 'http://localhost:8080/configs/keke' \
--header 'Content-Type: application/json' \
--header 'api-key: test_admin'

It should return 404

git fetch https://github.com/juspay/hyperswitch.git delete-config-api
git cherry-pick 089551b69e64f13968f93e1d3707e2262bac068b

Oh I need help, I think I have messed up, here what I did, I fetched the url you shared conflict aroused to accepted the incoming changes, then staged them and committed them as well, then ran the cherry pick command which responded with nothing to commit and when I am trying to push I am getting you have not concluded your cherry pick, can you help me figure it out.

I am not sure why would fetch cause conflicts, but
You can do something like

git cherry-pick --abort
git reset --hard 8ce4777a7023f268c6d022941c246f3ac8ea5bea

And continue with the above changes I suggested, Make sure you are on your branch where you are making changes
