F find query

Attention: f06ca944 must be checked carefully. Two separate changes affected the "WITH" statement. @daniel can you help/check?

Summary

The default behavior of the query FIND SomeName [...] (as well as COUNT and SELECT) is being made configurable and changes

1. FIND SomeName will be interpreted as FIND $FIND_QUERY_DEFAULT_ROLE SomeName from now on where FIND_QUERY_DEFAULT_ROLE is a newly introduced server property.
2. The new FIND_QUERY_DEFAULT_ROLE server property defaults to RECORD which is why the behavior of the server api has a breaking change.
3. Of course, administrators can choose to retain the old behavior by setting FIND_QUERY_DEFAULT_ROLE=ENTITY.

As requested per caosdb/customers/leibniz-zmt/management#98

Focus

Since the default role is configurable the changed code is executed after the parsing of the query string. This way, the parser did not change at all.

Test Environment

Tests in caosdb-pyinttest!45 (merged)
