Add command to return startup config (#459)
Add a new command that is able to return the set of configurations that that the
given instance of memgraph was started up with. The returned information
currently consists of the name, the default and the current value of each flag.
The hidden property of three flags were removed, namely --query-cost-planner,
--query-vertex-count-to-expand-existing and --query-max-plans. The flag
--log-link-basename was completely removed since it is not used.

ac230d0c2d Add basic queries for managing streams (#179)
* Add CREATE, START, STOP and DROP queries

* Fix definition of port in replica query

* Explicitly stop the consumer before removing

* Fix offset committing in Consumer

* Add tests for basic stream queries

* Remove unnecessary WITH keywords from CREATE query

* Add tests

* Add STREAM privilege

* Disable not working test

The functionality is tested manually, but I couldn't make it work with
the mock kafka cluster.

* Add support for multiple topic names

* Replace skiplist by synchronized map

* Make Consumer::Test const and improve error handling

The improvement in the error handling is mostly done regarding to the
Test function. Instead of trying to revert the assignments, Test just
stores the last commited assignment. When Start or Test is called, they
check for the last commited assignments, and if it is saved, then they
try to restore it. This way:
1. All the failures are returned to the user (failed to save/restore)
2. Failed assignment cannot terminate Memgraph

* Make Test do not block creating/droping other streams
