cli: allow specifying custom qcnl config when installing MarbleRun

[daniel-weisse]

Proposed changes

• Add a new flag to to marblerun install: --dcap-qcnl-config-file
  • Allows specifying the path to a qcnl config, which will be added to the Helm chart instead of using the default values in --dcap-pccs-url and --dcap-secure-cert
• The Helm chart similarly received a new settable value: dcap.qcnlConfig
  • Allows defining a qcnl config inline as a string
  • Alternatively the value may be set by reading a file using Helm's --set-file flag:

    helm install -n marblerun ./charts --set-file dcap.qcnlConfig=/path/to/sgx_qcnl.conf
    

• Update the default qcnl generated by the CLI and the Helm chart to use the newer JSON formatted config

I think this must be a json bool, not, e.g., "TRUE".

Fixed
Also added a fallback for older CLI versions that still supply this value as a string
