Proposed changes

Improve cli consistency by adding the --offline flag to the tedge reconnect command to allow users to reconfigure the mapper even if the device does not have cloud connectivity.

The offline mode is useful when the device has already been pre-registered with Cumulocity (via the Bulk Registration API), and the device is being setup in the factory without internet connection, and tedge connect/reconnect is used to recreate the bridge settings, and enable/start the required services (which is extremely helpful when dealing with non-systemd based OS's).

This aligns the tedge reconnect command with the tedge connect command, and allows users to seemlessly switch between the two commands,

Before

tedge disconnect c8y
tedge connect c8y --offline

After

tedge reconnect c8y --offline
