Store metadata title and description into the SQLite database

[p4u]

When a process is created, once the JSON metadata is fetch by the offchaindatahandler, store title and description of the process into the SQL database.

Then provide two new queries to search by terms on description and process and return the processess.

@mvdan do you think this search is possible?

what do you mean by "search by terms"? we could either do substring searches or "full text search" as described in https://www.sqlite.org/fts5.html.

This might do the job, yes.

I think vocdoni/interoperability#188 should be addressed first, since we may be storing information but won't be able to retrieve it since we don't have a way to properly filter and paginate results.
