[ADD] base_json_request: Module to allow standard JSON requests

[lasley]

• Create a module that circumvents the JSON-RPC requirement for all requests with application/json

This logic is taken from my REST API work in OCA/server-tools#889. It has been working well on multiple productions for a few months now. Note that none of these productions have multiple databases, which is an important detail in this instance (because this is a monkey patch).

That said, I do not intend to provide compatibility for multi-tenant here. I assert that the concept of a webhook and the concept of a multi-tenant Odoo instance are at odds with each other in most cases.

While multi-tenant is still a possibility while just using this module, the next PR I submit (base_web_hook - #4) will have an explicit note that this is not possible. IMO it is worth having the ability for a web hook, as long as the possible sacrifice is known. This may be possible to circumvent with database filters, but I haven't tested.

cc @moylop260 (I think you guys were looking for something like this for Gitlab webhooks)

Note: I still need to add tests, but the functionality is here to review.

Not

Add note that route needs to be defined with type=json

@lasley after oca-decorators, oca-jsonrequests 😏 Since this module is not designed to support multi-tenant and extend/fix the odoo api, it could be more appropriate to provide this functionality as a python lib. You can find a example on how you can monkey patch the odoo package from an other python package here https://github.com/acsone/odoo-autodiscover/blob/master/https://github.com/acsone/odoo-autodiscover/blob/master/.
In short odoo_autodiscover uses a Site-specific configuration hook (zzz_odoo_autodiscover.pth) to execute code during the initialisation of the python interpreter (https://docs.python.org/2/library/site.html)
As odoo_autodiscover you can use the wrapt python package to monkey patch Odoo. In your case you should maybe call the method wrap.wrap_function_wrapper from the hook file to patch Odoo. Here it's a link to an article describing how this lib can be use to monkey patch python code http://blog.dscpl.com.au/2015/03/safely-applying-monkey-patches-in-python.html.
IMO it's safer to provide this kind of monkey patch as a python package since this change is very intrusive and changes the Odoo api transversally.
It's my opinion and I'll not block this PR since you fix an annoying limitation in Odoo. Do you have tried to propose this change on Odoo master?

Thank you for the insight @lmignon

it could be more appropriate to provide this functionality as a python lib.

I think I agree with you, and I have no problem making this a lib instead. Thanks for the examples, they will keep me from redesigning wheels.

We do have a dissenting opinion on the using of external libs versus Odoo modules in OCA/server-tools#944 (comment) - the arguments I believe could be applied here as well. The overall strategy of using libraries is being questioned, so I'm going to bring this one over here & apply whatever we decide there to here too.

Oops forgot this point. I could look into this, yes. odoo/odoo#7766 (comment) seemed to allude to Odoo SA being willing to accept a patch, but I need this in v10 unfortunately. I'll likely submit something though, yeah.

We've observed that it's easier to propose enhancement on the core Odoo with PR on master. By doing this we've a chance to get this functionality supported into the next version of Odoo. In the meantime, the only solution to support this functionality is via an external lib.
