Support for TiDB

[hawkingrei]

TiDB is an open-source NewSQL database inspired by Google Spanner/F1 and aims for MySQL compatibility.

I've noticed some TiDB users are using Laravel with TiDB through MySQL protocol, and there'll be some inconviences due to:

• the unsupported features on MySQL compatibility.

• some extended features in TiDB, for example, the Sequence.

I've a plan for the further implmentation for TiDB with Laravel, please, let me know what you think about that. It would be appreciated if there's a speicifc guide for the database integrations.

Thanks!
