Deprecation proposal: Block build-id as a search attribute

[Shivs11]

What changed?

• A deprecation proposal to block the usage of build-id as a search attribute. Note, the changes introduced in this PR shall only emit warnings (for now) to analyze how many current users are actually doing this (expected number to be very low).
• Once we have a confirmation that the number of users who are using this are low, I will send a follow-up to error out when buildID is used as a SA.

Why?

• To prevent users from using pre-defined SA's.

How did you test it?

• [x] built
• [x] run locally and tested manually
• [x] covered by existing tests
• [x] added new unit test(s)
• [ ] added new functional test(s)
