Allow for multiple ReadyConditions

[MaciejKaszynski]

What

The config field should allow for a list of Ready Conditions to be set.

Config

Schema

• The flatbuffers config schema shall declare a ReadyCondition Union type of all the currently supported ready conditions.
• Change the component properties to ready_conditions and make it an array of ReadyCondition

CPP

This part might need some discussion.
How shall the ready conditions be stored?
std::vector? std::priotiy_queue?
with a priority_queue we could add a static member for PRIORITY for each ready condition implementation, then the order in which the ready conditions are processed can be defined?
Should the component implementation have it hard coded the order?

Component Implementations (process_info_node)

handleProcessStillStarting would need some changes as there we handle the ready conditions

Acceptance Criteria (DoD)

• Config allows for multiple ready conditions to be set.

How

Imo giving ready conditions priority and blocking on them will make it difficult for the user and complicate the implementation. They may not always have control over the order in which conditions are satisfied. Since we already poll for file state, I think it might make more sense to poll for all conditions, then we can simply iterate through the conditions in any order.
