Schedule weekly restart

[jhonabreul]

Description

Added a new ib-weekly-restart-utc-time option for users to be able to configure the IB weekly restart time so they don't miss the 2FA confirmation request.

The restart is scheduled to the configured time on Sunday:

• If IB shuts down before that, we wait until the configured time to start the gateway again.
• If IB doesn't shut down by the configured hour passes, we force restart manually.

Closes #34

Motivation and Context

IB weekly restart happens a random hours which can lead to users missing the 2FA confirmation request.
