An external cloud-specific object that the driver will use to login to the
external cloud. The structure of this object varies per driver
implementation.
It is recommended to have dedicated credentials for logging in to
the external cloud in order not to violate possible concurrent users
policies of the external cloud.
In case of the HERE Tracking loopback driver, the maximum
allowed concurrent user account tokens is 3 per account,
therefore it is recommended to create a separate HERE account
and grant it the required privilege to update the connector's
project, and use that account in externalCloudInfo.
