06531e01c5 database: disable hash/merge joins in FindLayer 
Our experiments have shown that PostgreSQL 9.4 makes bad
planning decisions about:
- joining the layer tree to feature versions and feature
- joining the feature versions to affected/fixed feature version and vulnerabilities
It would for instance do a merge join between affected feature versions (300 rows, estimated
3000 rows) and fixed in feature version (100k rows). In this case, it is much more
preferred to use a nested loop.

32747a5f25 database: Don't ignore empty results in toValue(s)() 
There is apparently no reason to ignore empty results - it was probably the case in the past (`null` value).

["", "v"] should be considered invalid by toValue() because it represents two values.
["", "v"] should be returned as it by toValues(), not trimming "".

Tests passes, it will hopefully not cause any issue in prod.

eb7e5d5c74 main: Use configuration file instead of flags and simplify app extension. 
Clair will now use a YAML configuration file instead of command line
arguments as the number of parameters grows.

Also, Clair now exposes a Boot() func that allows everyone to easily
create their own project and load dynamically their own fetchers/updaters.

cfa960d619 database: Update Cayley to fix slow deletions 
subject, predicate, object and labels are not indexed, thus, using a where clause on these fields for the DELETE statement does a full-table scan. Using *_hash columns instead will use the indexes.

b0142e1982 database: reduce pruneLocks/Unlock transaction. 
pruneLocks could create deadlocked transactions on PostgreSQL if multiple locks expired and pruneLocks is called by multiple instances. Also adds some logging.

7f1ff8f979 database: reduce InsertPackages transaction 
Inserting packages in a single transaction does not actually buy us anything as we often delete quads during an insertion and thus, Cayley could not use COPY and do a single round-trip. Inserting multiple packages in a single transaction actually creates deadlocks when a transaction tries to insert (A,B) and another one tries to insert (B,A).
