LDAP Support - Part 1

[jackyalbo]

Describe the Problem

We want to support authenticating to noobaa services using LDAP user/password for authentication
We will use assume_role_with_web_identity with self self-created JWT token of this structure:

{ 
  user: <user-name>, 
  password: <password> , 
  type: "ldap" 
}

signed by a jwt-secret saved under /etc/noobaa-server/ldap-config. looking like this:

{
  "uri": "ldap://192.168.105.16:636",
  "admin": "cn=admin,dc=planetexpress,dc=com",
  "secret": "GoodNewsEveryone",
  "search_dn": "ou=people,dc=planetexpress,dc=com",
  "dn_attribute": "uid",
  "search_base": "dc=example,dc=com",
  "search_scope": "sub",
  **"jwt_secret": "abcdefgh12345678"**
}

1. ldap_client
2. support assume_role_with_web_identity

Worth considering using openldap natively instead of adding this dependency. We should at least evaluate the effort to implement and maintain it.
