feat(api): openai compliant annotations and vector_content retrieval (#…

…1164)

* move vector type out of crud into typedef
* add common type for handling metadata
* add crud operation for retrieving vector and leapfrogai route
* fix: in chunk metadata use actual filename instead of tmp filename
* fix a typo in test data file
* refactor composer and converter to use vector content instead of file ids so it's easier to keep track of the vector_id's
