Device role and device site per device customization

[qduk]

Environment

• Nautobot version: 1.0.1
• aristacv-sync version: 1.0.2

Proposed Functionality

Rather than having a blanket default site and/or device role, provide some method that allows customizing the site and/or device roles applied to devices when imported.

Use Case

As an end user using the current state of the plugin, changing device roles and device sites must be down manually after importing data in Nautobot. Allowing for customization of device role and sites would streamline the import process.

Our initial idea for this is to allow an end user to provide a dictionary that maps substrings to site names as a plugin variables. An example would be something like the following:

PLUGINS_CONFIG = {
    "nautobot_ssot_aristacv":
    "site_mappings": {
        "nyc": "New York City",
        "atl": "Atlanta",
        "sfo": "San Francisco",
        "dal": "Dallas"
    }
}

We could check each device to see if any of the provided substrings exists in the device hostname. We'll take the provided value create the site in Nautobot if it doesn't exists and assign the device to that site.
