* 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
* Use the correct transformation result type
* Execute the result queries in streams
* Change the result type of parameters to nullable map
* Serialize transformation name
* Fix order of transformation parameters
* Use actual transformation in Streams
* Clear the Python transformations under GIL
* Add CHECK STREAM query
* Handle missing record fields properly
* Stop the Consumer grafefully when it is destroyed
* Add Streams
* Add Streams to InterpreterContext
* Remove options to limit processed batches in Consumer
* Add Streams unit tests
* Stop waiting for a full batch if the Consumer stopped
* Add ReadLock functionality to Synchronized
* Use per Consumer-based locking
* Replace shared_mutex with RWLock
This PR introduces READ COMMITTED and READ UNCOMMITTED isolation levels.
The isolation level can be set with a config or with a query for different scopes.
* Added handshake support
* Add support for v4 hello and goodbye
* Add support for pulling n results
* Add support for transactions
* Add pull n for the dump
* Add support for NOOP
* Add support for multiple queries
* Update bolt session to support qid
* Update drivers test with multiple versions and go
* Extract failure handling into a function
* Use unique ptr instead of optional for query execution
* Destroy stream before query execution

Summary:
The storage now uses a file in the data directory (`.lock`) to determine
whether there is another instance of the storage running with the same data
directory. That helps notify the user/administrator that the system is running
in an unsupported configuration.

This diff restores (and fixes) the old mg_import_csv implementation. The

Summary:
This only imports the `.py` files into the global interpreter. These
modules are not exposed to query execution. A later diff will add that
support.

Summary:
The configuration file that was used for the Debian/CentOS package was manually
written. This diff adds a configuration file generator that extracts all of the
necessary information about the flags directly from the built binary and uses
that information to generate the configuration file for the packages.

Summary:
The query execution now has a timeout for each Cypher query it executes. The
timeout is implemented using TSC and will work only when TSC is available (same
as PROFILE). TSC is used to mitigate the performance impact of reading the
current time constantly.

Summary:
All mgp_* symbols are exported from Memgraph executable, no other
symbols should be visible.
The primary C API header, mg_procedure.h, is now part of the
installation. Also, added a shippable query module example.
Directory `query_modules` is meant to contain sources of modules we
write and ship as part of the installation. Currently, there's only an
example module, but there may be potentially more. Some modules could
only be installed as part of the enterprise release.
For Memgraph to load custom procedures, it needs to be started with a
flag pointing to a directory with compiled shared libraries implementing
those procedures.

Summary:
Depends on D2471
- Add pointer to storage to `InterpreterContext`
- Rename `operator()` to `Prepare`
- Use `Interpret` instead of `operator()` (`Interpret` will be removed soon)
- Remove the `in_explicit_transaction` parameter
- Remove the memory resource parameter from `Interpret`
- Remove the storage accessor parameter from `Interpret`
- Fix up tests (remove the `Interpreter` from `database_transaction_timeout`)

Summary:
This diff splits single node and distributed storage from each other.
Currently all of the storage code is copied into two directories (one single
node, one distributed). The logic used in the storage implementation isn't
touched, it will be refactored in following diffs.
To clean the working directory after this diff you should execute:
```
