Create a Resolve Host/DCC in Shift to declare the operators like Resolve operators #5

Right now the operators from Shift_Resolve catalog are not defined like operators from a DCC. This allows us to create the operators and create workflows outside Resolve, However at some point we should improve this and add the Resolve DCC to Shift to keep track over the DCC in use.

Description

We should take care of different things:

• Create a Shift method to Open resolve inside Resolve. This method may be a plugin for Shift included in this Repo, but we should check if Shift allow us to create Shift executions from upside, like a plugin.
• Declare all the operators like "Resolve" operators.
• (Suggestion) Even if we declare the Resolve operators for the DCC, it would be nice to have the option to create the operators from outside Resolve. This is more like a Shift Issue, but we should check at this point if we can allow the operators creation from outside the DCC in someway, like a preference to load the catalog even if Resolve is not the Host. (All the operators have a check to raise an error if Resolve is not available, so is not a problem for the execution)
