Cannot create a dataset with Presto DB

[kaypark-skt]

Describe the bug

when creating a dataset with presto db

1. /api/connections -> get a connection
2. /api/connections/query/check -> using the connection. it is ok.
3. /api/connections/query/databases -> using the connection. a few properties missing.

i heard that
presto needs a parameter of catalog.
postgresql needs a parameter of database.

To Reproduce

1. create a Presto DB connection
2. create a dataset with the connection.

you can see this message.

"code":"JDC0003",
"message":"Fail to get list of database : StatementCallback; uncategorized SQLException for SQL [ SELECT schema_name FROM information_schema.schemata WHERE catalog_name = 'null' ORDER BY schema_name ]; SQL state [null]; error code [1]; Query failed (#20190306_071107_00020_2eybd): line 1:27: Catalog must be specified when session catalog is not set; nested exception is java.sql.SQLException: Query failed (#20190306_071107_00020_2eybd): line 1:27: Catalog must be specified when session catalog is not set"
