tensorboard prototypes should include the optionalParams available in that prototype

[kkasravi]

for example
ks param list tensorboard-aws
should return something like

COMPONENT       PARAM                          VALUE
=========       =====                          =====
tensorboard-aws logDir                         'logs'
tensorboard-aws name                           'tensorboard-aws'
tensorboard-aws s3AwsRegion                    'us-west-1'
tensorboard-aws s3Endpoint                     'http://s3.us-west-1.amazonaws.com'
tensorboard-aws s3SecretAccesskeyidKeyName     'null'
tensorboard-aws s3SecretName                   'null'
tensorboard-aws s3SecretSecretaccesskeyKeyName 'null'
tensorboard-aws s3UseHttps                     'true'
tensorboard-aws s3VerifySsl                    'true'
tensorboard-aws serviceType                    'ClusterIP'
tensorboard-aws targetPort                     6006
