🐛 fix(azure devops): fix migration version on a fresh install

[iamrajjoshi]

when the integration is freshly installed, we need to make sure the migration version number is set to 1 as we use this metadata to determine what method we will use to refresh the tokens.

i wrote tests to make sure we refresh correctly when a new integration is installed as well.

to completely fix the bug, we need to do a backfill for all new integrations to update the metadata so we can grab the refresh correctly.

Q: who will go under this feature flag ?

Q: who will go under this feature flag ?

we already use this ff to gate if we use the new devops integrations or not. though its currently ga'ed, using the flag will make rollback easier if needed. we will eventually remove this flag
