Resolve "Inter-entry reference resolution in client, cli, and archive reader"

• add functionality to resolve references to different archives on the same server, using the provided user credentials
• add a simple test which involves references to both the same and a different archive

A few points:

1. References to another installation (a remote url such as: https://his.oasis/uploads/some_upload/archive/some_archive#path/relative/to/entry) will not be resolved accounting for the fact that there may not be access to that installation, even with the provided user credentials.
2. All references to another entry are resolved by:
   • Retrieve the plain json data from the public API answer_entry_archive_request
   • Apply the same required to extract relavent data. At this stage, there is no need to distingush whether another entry is in the same upload or another upload. Using answer_entry_archive_request handles both case uniformly.
3. In the case of references need to be resolved but not in-place, the current implementation adds the same data structure to the result json, this leads to data overlapping for references like entry_a#/run/0/system/0 and entry_b#/run/0/system/0. All references to another entry are prefixed by the corresponding entry id to avoid data overlapping. See the example for comparision.

The example archive has a reference to XUlSxqEvec0LvPQbSLWeysB1Ksns,

{"workflow":[{"calculation_result_ref":"../uploads/examples_template/archive/XUlSxqEvec0LvPQbSLWeysB1Ksns#/run/0/calculation/0"}]}

which further has references to itself.

{"run":[{"calculation":[{"system_ref":"/run/0/system/0","method_ref":"/run/0/method/0","energy":{"total":{"value":-1.5935696296699573e-18},"free":{"value":-1.5936767191492225e-18},"total_t0":{"value":-3.2126683561907e-22}}}]}]}

After resolving all references, it becomes (other associated data is removed here for clearer presentation):

{
  "XUlSxqEvec0LvPQbSLWeysB1Ksns":{
    "run":[
      {
        "calculation":[
          {
            "system_ref":"/XUlSxqEvec0LvPQbSLWeysB1Ksns/run/0/system/0",
            "method_ref":"/XUlSxqEvec0LvPQbSLWeysB1Ksns/run/0/method/0",
            "energy":{
              "total":{
                "value":-1.5935696296699573e-18
              },
              "free":{
                "value":-1.5936767191492225e-18
              },
              "total_t0":{
                "value":-3.2126683561907e-22
              }
            }
          }
        ]
      }
    ]
  },
  "workflow":[
    {
      "calculation_result_ref":"/XUlSxqEvec0LvPQbSLWeysB1Ksns/run/0/calculation/0"
    }
  ]
}
