Security credentials provider for specifying security credentials.
Security credentials used for node authentication.
Getting credentials through SecurityCredentialsProvider abstraction allows
users to provide custom implementations for storing user names and passwords in their
environment, possibly in encrypted format. Ignite comes with
SecurityCredentialsBasicProvider which simply provides
the passed in login and password when encryption or custom logic is not required.
In addition to login and password, security credentials allow for
specifying userObject as well, which can be used
to pass in any additional information required for authentication.
