ee5e64408d examples: common code for data loading
This also moves SimParams handling to a single place. As a result,
path_requests_run has just become Raman-aware (to the minimal possible
extent, OK).

648039521e reorganization: move all JSON processing into an extra module
We agreed that `gnpy.core` should only contain stuff for propagating
wavelengths. Conceptually, JSON parsing and even instantiating these
network elements from data obtained through JSON is *not* something that
is on the same level -- and this will become more important when we move
into YANG format in future.

Also, instead of former `gnpy.core.equipment.common`, use
`gnpy.tools.json_io._JsonThing`. It is not really an awesome name :),
but I think it sucks less than a thing called "common" which would be no
really longer any "common" in that new file.

de58d7d7c2 Enable ILA and FUSED type in routing constraints with xls input
- builds correspondance dicts between input name from excel
  and names created with convert.py and autodesign in network.py
- correct the corresp_name dicts according to the effective
  network autodesign. This supports the case of fiber splitting
  and of fused elements
- include the case of parrallel links with only one hop
- interpret the node list constraint given by the user with the dict
- filter the constraints that are not applicable
- add tests for constraints
- correct equipment sheet of mesh_example_topologyv2.xls: morlaix and
  loudeac should not appear in node A column since they are fused

ILA and FUSED constraints must be filled with the next node
information in order to avoid confusion on the direction.
for example
     eg    a----b-----c
           |    |     |
           i    j     k
           |    |     |
           e----f-----g

a constraint 'j' given for service i to k leads to 2 possible direction:
i-a-b-j-f-g-k
i-e-f-j-b-c-k
the user must indicate the chossen direction. This ambiguity does not
exist with network input in json format (names are unique).

In compute_path_with_disjunction, and in case user mode is not feasible
returns the blocking reason instead of an empty path.
If the user does not give the mode and the automatic selection does not
give any feasible mode instead of checking if a mode exists, the function
now checks the presence of a blocking reason.

if the blocking reason is among BLOCKING_NOPATH reasons, than an empty
path is returned
if the blocking reason is among BLOCKING_NOMODE, then a path could be computed
and the mode information correspond to the last explored mode.

8af2d80219 Add reasons for blocking in the response
Before continuing on spectrum assignment we need to clearly identify blocking reasons:
implicit previous way (a path is missing) is not satisfactory because in case of
spectrum blocking a path was possible. So we introduce a 'blocking_reason' attribute
on requests, that will only exist if the path is blocked during the process.
The 'blocking_reason' attribute refflects the blocking reason.
Commit defines blocking types and group them depending on the existence of path or
feasibility:
    'NO_PATH': no path was computed,
    'NO_PATH_WITH_CONSTRAINT': no path was computed with this constraint
    'NO_FEASIBLE_BAUDRATE_WITH_SPACING': no path was computed due to the spacing constraint
    'NO_COMPUTED_SNR': the computed path could not give any SNR result
    'NO_FEASIBLE_MODE': the user let the program choose a mode and path was computed but
                        no mode was feasible for the set of constraints
    'MODE_NOT_FEASIBLE': the user imposed a mode, a path was computed but this mode
                         is not feasible
    'NO_SPECTRUM': a path, a mode were selected but there is not enough spectrum available on
                   this path
