New adapters based on 3rd party vendors

[chriskapp]

Currently we have build adapters mostly for basic infrastructure topics i.e. Mysql, Postgres, Mongodb, Elasticsearch, etc. To improve the no-code aspect of Fusio we are planning to build new adapters for multiple different vendors. Through this users could easily require such adapters and start build an API using those services with either no code or only a little bit glue code. This issue simply contains a list of vendors which we could integrate. If you are interested in a specific provider please let us know:
