Detect when trying to create a record with the same title as an existing record

[mhucka]

After seeing the results of a user's attempts to update records without using --draft and subsequently creating multiple identical-looking entries in our RDM server, it seems it would make sense to have IGA check the server for records with identical titles to the record about to be created.

Current thinking:

• This should be an error by default
• There should be a flag to force the creation if the user really wants it

API call to https://data.caltech.edu/api/records?q= with query metadata.title:"TITLE". Example https://data.caltech.edu/search?q=metadata.title%3A%22motifs%20%E2%80%93%200.1.0%22

Note to self: here is the URL to search in InvenioRDM for the title "Boffo – 1.4.0":

https://data.caltech.edu/api/records?q=metadata.title%3A%22Boffo%20%E2%80%93%20Release%201.4.0%22

This is basically

metadata.title:"Boffo – Release 1.4.0"

with %-encoding. It needs to be double quotes, and note the : after metadata.title (and not an =).
