Implement read and create benchmark in Nextras ORM

[repli2dev]

Hi, I have implemented the tests create and read in Nextras ORM (#23).

[sergeyklay]

@repli2dev Could you please README.md? You'll need to amend table with results and build id from the Travis CI

[repli2dev]

@sergeyklay I will do, however I am having some troubles making it work on Travis CI as I am getting: Nextras\Dbal\QueryException: Unknown or incorrect time zone: 'UTC' on /home/travis/build/sergeyklay/php-orm-benchmark/provider/nextrasorm/vendor/nextras/dbal/src/Drivers/Mysqli/MysqliDriver.php:381 which typically means that I need to add timezones to the MySQL and I don't know the prefered way.

@repli2dev

The known approach to fix it is add this command to before_script section:

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

Have a nice day

[repli2dev]

@sergeyklay Now it has executed properly, however I am a bit puzzled which results are which in the CI to update the README.

[sergeyklay]

@repli2dev Let me update results a bit later. Thank you for the contributing, and for helping make benchmark better.

Thanks... Ping me when other operations will need implementation.
