Julia calibrate initial UI refactor

[Jami159]

This code strips out the code from tera-calibrate-node-julia.vue and puts it in tera-calibrate-julia.vue.
This isn't the final version of the workflow node or the drilldown.

Open questions/concerns that need to be fixed in the future/separate PR:

• What should the workflow node show after a calibrate was started from the drilldown and a user exited out of the drilldown?
• What should happen while a calibrate is running but a user has exited out of the drilldown?
  • to further clarify on this point, because the the drilldown component gets unmounted when it's closed, we stop querying the message queue, so in that time the simulation could finish running but we may not have all the intermediate results? (TODO: still need to verify the exact details of what happens in this scenario)

Resolves #2248
