BloodHound customqueries: refacto for clarity, performance, fix and new queries

[gbe]

This PR aims at improving the custom queries for Bloodhound.

To do so, I refactored many queries to:

• standardize a bit more the formatting while reducing the queries length
• improve the performance of queries by adding more criteria to reduce the set of nodes Neo4j must take into account when computing the results, the flag enabled is a typical example
• remove useless subqueries
• improve the regexp for the queries checking for plaintext password
• fix a bogus request
• one query was not doing what the comment said it would
• add more indexes
• add one nice query I wrote: Administrators and Domain/Entreprise Admins with sessions not on domain controllers

Nice!
