AsyncZabbixAPI can't be used in with statement like ZabbixAPI

[orhantugrul]

The AsyncZabbixAPI class cannot be used in a with statement like the ZabbixAPI class. This is due to a difference in the initialization process between the two classes.

Current Behavior

• ZabbixAPI automatically logs in during the __init__ function.
• AsyncZabbixAPI does not automatically log in during initialization.

Expected Behavior

Users expect to be able to use AsyncZabbixAPI in a with statement similar to ZabbixAPI for consistent usage patterns.

Proposed Solution

Perform the asynchronous login in the __aenter__ method.

class AsyncZabbixAPI:
    async def __aenter__(self):
        await self.login()
        return self
