Feature/new cxml model

[GilianJuice]

Describe your changes

Added models that we need for Open Catalog Interface (OCI) connections. Also fixed a bug that cookie was immediately deleted after logging in with a session cookie. This was already fixed in the JCL the same way, but we never copied that fix to the GCL until now.

Type of change

Please check only ONE option.

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How was this tested?

I tested if these models can be deserialized and serialized from and to XML. Nothing else to test.

There are inconsistencies in the attribute format across the various models. The attributes in some models contain whitespace characters before and after the = sign, whereas other models don't. So some use this format:

[XmlAttribute(AttributeName = "version")]

While others use this format:

[XmlAttribute(AttributeName="version")]

Please use one style to make it consistent. I noticed that the majority of the models use the second style (so without the the whitespace characters) so it's probably easier/faster to update using that style.

Sorry, I used an external tool to generate these classes from an example XML. I didn't notice these differences. Fixed them now.

There are still a few models that use a different format for the attributes (such as BillToModel and ChargeModel), but as it doesn't really affect anything I'm approving the PR.
