This PR includes: Fixes; Robustness improvements to ros_typedb (resilient to DB being deleted on the fly, DB crash, ros_typedb lifecycle change etc) ; Improvements to how errors are logged, more stuff should be logged now; and a new package ros_typedb_benchmark which contains code to "stress" test ros_typedb.
I will write a proper CHANGELOG tomorrow.
The "stress" test was really useful. For example, it showed that querying typedb in very high rates is not really a problem, and help me find some bugs.

@EGAlberts There are some fixes that are related to the problems you had in case you still wanna try using typedb for eval2:

1. Using the force_database parameter for reusing the DB without removing the schema was incorrect. I added a new reload_schema parameter. Just set it to False when you dont want the schema to reload. Check: cc4c15e
2. There was a bug with fetch queries that fetched all attributes of a thing, i.e., match $a isa entity; fetch $a: attribute;. Check: ccce260

If you try to use this branch you will probably need to update the constructor of the typedb interface for tactical retreat

sounds great @Rezenders , with the 2.9 version it seems things are working better, so hopefully we can keep using typedb

Actually @Rezenders now it seems to be failing in the same way, after trying to run it more extensively..
