40b086d6 - Allow to specify ID when adding to the FAISS vectorstore. (#5190)

Allow to specify ID when adding to the FAISS vectorstore. (#5190) # Allow to specify ID when adding to the FAISS vectorstore This change allows unique IDs to be specified when adding documents / embeddings to a faiss vectorstore. - This reflects the current approach with the chroma vectorstore. - It allows rejection of inserts on duplicate IDs - will allow deletion / update by searching on deterministic ID (such as a hash). - If not specified, a random UUID is generated (as per previous behaviour, so non-breaking). This commit fixes #5065 and #3896 and should fix #2699 indirectly. I've tested adding and merging. Kindly tagging @Xmaster6y @dev2049 for review. --------- Co-authored-by: Ati Sharma <ati@agalmic.ltd> Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>
