Add mapping for complex attributes

[RogerSelwyn]

#684

In support of this issue, this adds the ability to convert a select attribute from a simple attribute to a complex one required by MS Graph.

First I have write a new Query class that I want to replace the old one.
You can check it here.

Also I've added a comment on a line that needs to change.

Also, I will be thankful if you can try the new Query.
It works like this:

# here you have you account set up:
from O365.utils import ExperimentalQuery

builder = ExperimentalQuery(protocol=account.protocol)

query = builder.equals("name", "James") | builder.equals("address", "james@example.com")
query = query & builder.orderby("name", "address")

# then use query as where the old query was used in the same way

For example to add select just mix whatever part with builder.select with the & operator

Also, I will be thankful if you can try the new Query. It works like this:

The reasons for a new query builder are:

• Allows for more deep operations like using iterator like any or all over complex attributes or deep collections
• It's way more simple and error prone.
• It allows for the use of & and | operators (but also implements `builder.chain_and/chain_or")
• It allows to group filters explicitly in the way you like with builder.group
• It properly manages the negate condition being explicit about it's use with builder.negate
