Code Issues Proposed changes

Add generic fuzzy matching logic to the database layer 

share snap list, Fuzzy query by name or description is supported, but
the current implementation is first get all the shares, then In the API
layer, the for loop is used to achieve fuzzy matching, if the num of
shares is big,
It will seriously affect the speed of fuzzy matching.Therefore, we
should let the database do the matching to speed up the query.
Moving the pagination params (limit, offset, sorting) to the database
layer for snapshot list, to optimize query speed.

Closes-Bug:#1881865
Partial-Bug:#1831094
