Becplotter new config fix

Description

The new config hierarchy introduced in bec-widgets!31 is not compatible with the previous version of BECPlotter to launch plotting from CLI.

Related Issues

• closes #154 (closed)

Type of Change

• BECPlotter default config changed to new style
• BECPlotter set_xsource, set_ysource and label changes adapted to new configs
• BECPlotter all redis related methods refactored to include tags which can be picked up by BECMonitror during database creating

Potential side effects

• The changes to source redis are to working, I would like to discuss how the BECMonitor should be adapted.
• Changes of source and labels are not refreshed with BECPlotter.refresh(), to change configuration one has to close and show the plotter window to see the changes.
• ATM BECMonitor can access the msg from redis with data send, however ATM no plotting logic

        "axis_width": 2,
        "num_columns": 5,

            "y": {"label": "bpm4i", "signals": [{"name": "bpm4i"}]},
        }
    ],
