Add global limit

[jannyHou]

Description

Specify a config variable globalLimit in your datasource file:

myCloudantDs: {
  url: <a_url>,
  database: <a_database>,
  globalLimit: 100
}

It will override the default limit(which is 25) in cloudant database.

Please note: The query level imit in function Foo.find({limit: <a_query_level_limit>}), should override the globalLimit, which is not implemented in this quick fix PR.

The precedence is:

• count, destroyAll: globalLimit > cloudant default limit value 25
• find: query level limit > globalLimit > cloudant default limit value 25
