for compatibility with login/password

Because this was broken, we took the liberty to introduce a breaking
change to fix naming, now type based scripts are *_getUserValue and must
return a user document, with a getUserId method returning the user id.

Make this plugin also an IAuthenticationPlugin which does all the job of
returning the user id.
It does not really make sense to delegate this to default authenticator.
A side effect is that token can still authenticate users with no
assignments, since tokens are scriptable, if this is a requirement, it
can be implemented in scripts.

also update test:

 - plugin must be enabled for IAuthenticationPlugin
 - check complete authentication sequence, not just extraction
 - update scripts to new names
 - simplify transaction management
 - don't set self.person, it was not used anywhere
 - update _createPerson to reindex, as said in docstring
 - merge all tests in on test component

This revert https://lab.nexedi.com/nexedi/erp5-capago/merge_requests/37
which was a backport of an intermediate state of
nexedi/erp5!838

Revert this first backport to easily backport again the latest merged

no need to use different test components

also update _createPerson to reindex, as said in the docstring

 - plugin must be enabled for IAuthenticationPlugin
 - check complete authentication sequence, not just extraction
 - update scripts to new names

As script return user_ids it's more logical to name them *_getUserId

tests for booking in french language from https://lab.nexedi.com/nexedi/capago/merge_requests/363  needs it, probably on production it should not change anything as with "real zopes" we set the encoding in zope.conf.

zope.conf default encoding is also used for responses and converters, so
for consistency we should also force default encoding there.
This is especially useful when running tests, because zope.conf is not
used and default values are used.

https://tools.ietf.org/html/rfc4329#section-7 states that text/javascript is obsolete.

Doesn't really matter in the end because WebPage_viewAsWeb forces the content type.

In HTTP/1.1 , when not specified , charset detault to ISO-8859-1

https://tools.ietf.org/html/rfc2616#section-3.7.1

> media subtypes of the "text"  type are defined to have a default charset value of "ISO-8859-1" when   received via HTTP

Zope adds a charset with default encoding (
https://github.com/zopefoundation/Zope/blob/2.13/src/ZPublisher/HTTPResponse.py#L512-L515 ) but does this only for text/ type, but we serve our javascript as application/javascript

According to pep-0263, python scripts can define encoding magic on
first or second line.
If we use for example such a script:

```python
  # coding: utf-8
  return "héhé"
```

then using .read() was wrong, because it return the script with headers,
ie:

```python
  ## Script (Python) "test_coding"
  ##bind container=container
  ##bind context=context
  ##bind namespace=
  ##bind script=script
  ##bind subpath=traverse_subpath
  ##parameters=
  ##title=
  ##
  # coding: utf-8
  return "héhé"
```

so the coding magic is no longer in first line and pylint complains
with error like:

Cannot decode using encoding "ascii", unexpected byte at position 11 (invalid-encoded-data)]

Using a cache cookie that is incremented each time an account is added or modified,
we can keep an (almost) up to date list of accounts in the UI.

Just set indentation rules for now

Because typescript is a subset of javascript, running typescript
compiler on javascript files can already report several issues.

This is triggered by using "Format document" from context menu.
