6fe474282a Modify logaical operators to conform openCyper regarding checking against NULL in CASE expressions (#432) 
* Make `IfOperator` return the `else_expression_` in case of `NULL`

* Add gql_behave tests

* Add gql_behave test to specifically check for the case when the test expression itself is null

7fc0fb6520 Implement ToString function for temporal datatypes (#429) 
* Modify `toString` to be able to handle `Date`, `LocalTime`, `LocalDateTime` and `Duration`

* Add unit tests

* Make `operator<<` use the `ToString()` implementations

* Add tests to verify the correctness of negative durations

* Add more tests to look for cases when the individual duration entities overflow.

f629de7e60 Save replication settings (#415) 
* Storage takes care of the saving of setting when a new replica is added

* Restore replicas at startup

* Modify interactive_mg_runner + memgraph to support that data-directory can be configured in CONTEXT

* Extend e2e test

* Correct typo

* Add flag to config to specify when replication should be stored (true by default when starting Memgraph)

* Remove un-necessary "--" in yaml file

* Make sure Memgraph stops if a replica can't be restored.

* Add UT covering the parsing  of ReplicaStatus to/from json

* Add assert in e2e script to check that a port is free before using it

* Add test covering crash on Jepsen

* Make sure applciaiton crashes if it starts on corrupted replications' info

Starting with a non-reponsive replica is allowed.

* Add temporary startup flag: this is needed so jepsen do not automatically restore replica on startup of main. This will be removed in T0835
