示例1: startContainerInternal

/*
* 1) It should save the NMToken into NMTokenSecretManager. This is done
* here instead of RPC layer because at the time of opening/authenticating
* the connection it doesn't know what all RPC calls user will make on it.
* Also new NMToken is issued only at startContainer (once it gets renewed).
*
* 2) It should validate containerToken. Need to check below things. a) It
* is signed by correct master key (part of retrieve password). b) It
* belongs to correct Node Manager (part of retrieve password). c) It has
* correct RMIdentifier. d) It is not expired.
