Bug#896810: Packaging node-lemonldap-ng-handler

[Xavier <yadd@debian.org>]

Dear ftp masters,

here is a resume of dependencies of node-* packages needed for
node-lemonldap-ng-handler.

node-lemonldap-ng-handler is an alternative engine for lemonldap-ng
Web-SSO (when used with Nginx). It will be usable also to provide
SSO-as-a-Service which comes with lemonldap-ng 2.0 (will be released
around 2018-10).

Here is the tree of its dependencies (new only):

* Required:
  - node-file-cache-simple:
    - node-fs-jetpack
  - node-inireader
  - js-md5
  - aes-js

* Recommended
  - node-modern-syslog

Session backends are inspired from Apache::Session (Perl) to be
compliant with lemonldap-ng. Usr has to choose between: File (native),
LDAP, SQL or MongoDB. Theses new packages are proposed in this goal:
- node-ldap-client
- node-nodedbi
- node-mongodb:
  - node-mongodb-core:
    - node-bson
    - node-require-optional
      - node-bson (build)

I hope this resume will clarify this proposed packages. Some of them
will be also useful for many other packages (node-nodedbi,
node-ldap-client, node-mongodb,...)

Best regards,
Xavier
