Functionality to refresh token after a set amount of time

[ralkan]

With this PR you request a new token after a set amount of time. Sometimes tokens can become invalid after some time and this has been implemented to get around this issue.

In your django settings you can now import from mssql.base import BaseTokenManager and use it like so:

class MyTokenManager(BaseTokenManager):
    invalidate_seconds = 900  # 15 minutes

    def get_token(self):
        credential = identity DefaultAzureCredential(exclude_interactive_browser_credential=False)
        token = credential.get_token("https://database.windows.net/.default").token
        return token

And then in your DATABASES you do:

DATABASES = {
    'default': {
        'ENGINE': 'mssql',
        'TOKEN': MyTokenManager(),
        ...
}
