v15 version of VTOrc is incompatible with 2.7.* versions of Vitess Operator and v14 version of VTOrc is incompatible with 2.8.* versions of VTOrc.
So when the users upgrade from 2.7.* version of Vitess Operator to 2.8.*, they should also update their deployment of VTOrc.
The VTOrc can be configured to run for a given keyspace by specifying the vitessOrchestrator specification as part of the keyspace spec.
Resource limits and requests can be specified as part of the configuration and the default behaviour of VTOrc can be changed by specifying any
desired flags in the extraFlags field.
The VTOrc UI runs on the port 15000 of the container and port-forwarding can be setup to access it.
Previously, VTOrc deployment also took a configuration file as a secret specified in the configSecret parameter. This field has been removed in this release of Vitess Operator.
