Dish ID-VCC Map

Implement the Dish ID-VCC Map as per https://confluence.skatelescope.org/display/SE/DishID-VCC+Map+Design

Includes:

• Add new command on CbfController to provide initialization parameters
• Add checks to ensure obs state and ops state allow the command to be received; reject if not
• Provide read attribute on CbfController to provide the parameters in use (json)
• Store updated receptor to vcc mapping, k values, and deltaF provided in the command in CbfController, CbfSubarray. Update VCC as needed
• Remove read/write k attributes from Cbf Controller, Cbf Subarray (replaced with json passed in new command)
• Command documentation added to RTD: https://developer.skao.int/projects/ska-mid-cbf-mcs/en/latest/guide/interfaces/lmc_mcs_interface.html#cbfcontroller-tango-commands 
• Add json schema to Telescope Model
• Validate command input using the json in Telescope Model
• Add unit and integration tests to send the command and ensure updates are made as expected
• Add to LMC Interface in EC to exercise the command
• Add command to BDD tests before sending ON command - the input file from the command is required before On can be called
• Minor refactoring in MCS Controller, Subarray and VCC to pass down the fs_sample_rate calculated in the CbfSubarray to the VCC instead of passing k and deltaF values down and calculating fs_sample_rate in VCC (keep the calculation in one place). This follows the same pattern used for FSP - see "Implementation Consideration" in https://confluence.skatelescope.org/display/SE/Mid.CBF+FSP-Part+Control+Design#Mid.CBFFSPPartControlDesign-2.4SystemConstantParameters
