* MVStoreDAO implementation for citations relations (#11189):

* Solve task 1
* Implementation of a DAO chain: memory cache and MVStore
* Persist citations as relations to disk after a fetch
* Avoid fetching data if relations are available from MVStore
* Avoid reading data from MVStore if available in memory
* Consume less from network, minimize disk usage

* Implement a search lock mechanism for citations relations (#11189):

* Solve part of task 2: make impossible to force a search on a BibEntry over a week since last insertion
* The MVStoreDAO search lock is based on a timestamp map (doi -> lastInsertionDate)
* All time computation are based on UTC
* The LRU cache will always return true -> the computer could stay up during a week, leaving cache in memory

* Avoid user to force update citation relations even the fetcher returned an empty list

* Solve completely Task 2: make impossible to force a search on a BibEntry over a week since last insertion

* Make the citation relations update automatic after the guard delay is exhausted

* Remove the isForceUpdate boolean
* User is still able to trigger the fetch if an error occurs

* Inject service in EntryEditor
