unfortunately the API changes introduced in change
I277aa90fddb5171c4bf6c3436259aa371d30d092
broke the API interface of http_json_api.py. This was taken into
account and necessary to introduce add the server functionality next
to the already existing client functionality. The changes to the API
were minimal and all code locations that use http_json_api.py
were re-aligned.
Unfortunately it was not clear at this point in time that there are
out-of-tree projects that could be affected by API changes in
http_json_api.py
To mitigate the problem this patch introduces an alternative API
interface to the JsonHttpApiFunction base class. This alternative
API interface works like the old API interface when the class is
instantiated in the original way. To make use of the revised client
the API use has to pass an additional keyword argument that defines
the role.

Main points/rationales of the refactoring, details below:
1) common validation implementation
2) offer classmethods
The new features are optional, and will be heavily used by batch
personalization patches coming soon.
Implement Iccid and Imsi to use the new way, with a common abstract
DecimalParam implementation.
So far leave the other parameter classes working as they always did, to
follow suit in subsequent commits.
Details:
1) common validation implementation:
There are very common validation steps in the various parameter
implementations. It is more convenient and much more readable to
implement those once and set simple validation parameters per subclass.
So there now is a validate_val() classmethod, which subclasses can use
as-is to apply the validation parameters -- or subclasses can override
their cls.validate_val() for specialized validation.
(Those subclasses that this patch doesn't touch still override the
self.validate() instance method. Hence they still work as before this
patch, but don't use the new common features yet.)
2) offer stateless classmethods:
It is useful for...
- batch processing of multiple profiles (in upcoming patches) and
- user input validation
to be able to have classmethods that do what self.validate() and
self.apply() do, but do not modify any self.* members.
So far the paradigm was to create a class instance to keep state about
the value. This remains available, but in addition we make available the
paradigm of a singleton that is stateless (the classmethods).
Using self.validate() and self.apply() still work the same as before
this patch, i.e. via self.input_value and self.value -- but in addition,
there are now classmethods that don't touch self.* members.

At the moment http_json_api only supports the client role. Let's also add
support for the server role.
This patch refactors the existing client code. This in particular means
that the following preperations have to be made:
- To use the existing JsonHttpApiFunction definitions in the client and
server the scheme has to be symetric. It already is for the most part,
but it treads the header field differently. So let's just treat the
header field like any other mandatory field and add it input_params.
(this does not affect the es9p.py code since in ES9+ the requests have
no header messages, see also SGP.22, section 6.5.1.1)
- The JsonHttpApiFunction class currently also has the code to perform
the client requests. Let's seperate that code in a JsonHttpApiClient
class to which we pass an JsonHttpApiFunction object.
- The code that does the encoding and decoding in the client role has
lots of conditions the treat the header differently. Let's do the
decisions about the header in the JsonHttpApiClient. The encoder
and decoder function should do the generic encoding and decoding
only. (however, some generic header specific conditions will remain).
The code for the server role logically mirrors the code for the client
role. We add a JsonHttpApiServer class that can be used to create
API endpoints. The API user has to pass in a call_handler through which
the application logic is defined. Above that we add an Es2pApiServer
class in es2p. In this class we implement the logic that runs the
HTTP server and receives the requests. The Es2pApiServer supports all
ES2+ functions defined by GSMA SGP.22. The user may use the provided
Es2pApiServerHandler base class to define the application logic for each
ES2+ function.
