ASM-6521, ASM-6522 Make discovery scripts recognize credential_id

To support server and chassis discovery scripts to accept credential_id as parameter, ASM deployer's run_script will pass credential_id as command line arguments to any discovery scripts (similar to passing other generic arguments like username,password,output,community)string).

This means Trollop of the discovery scripts needs to declare accepting credential_id param, even if it is no-op.
