Implement cookie auth security (or another if possible)

[VigneshVSV]

To authenticate access to the hardware through HTTP, cookie auth needs to be added.

A separate branch has already been created for this.

Basic idea code (which also works) is available in release v0.1.2 under system_host folder. The logic is as follows

• cookie secret is generated (needs to be given by the user?)
• There's a permanent database which holds information about the credentials and a SQLite in memory database which holds a login entry after the given credentials are validated
• necessary headers are set and credentials are verified for each request

Possible steps

• Integrate this logic , the separated branch has only started the integration, but not completed
• Write a dataclass or similar, which will accept information from the user what are the credentials
• For each property, action and event, support separate credentials. By default, the Thing level credential must be supported for each property, action and even, but can be fine-tuned on case by case basis
• Update TD generation logic to add information about security schemes, including interaction affordance specific security
• Add a flag at class level allow_unauthorized_access, which has to be set to False if a HTTP server will be used. This should be the default behaviour to force the user to think about security.
• Add tests

Same may be done for another security method as well. I do not know how to code other security schemes.
