Refactor [global_]|options within component(s) and their inheritance among components

[pmoravec]

Splitting #3746 (comment) to a separate issue (that should be again dealt indepentently on upload feature). Current code - (without or in-near-future with) upload subcomponent - suffers by:

• global options are "not so global" (e.g. neither apply to help, some dont apply to clean, many wont apply to upload). The idea of global options does not scale well with our current components. We shall revisit this approach.
• currently, each component "enumeratively" declares each and every option it supports, namely those "shared among some other components". And passing lists of options among components is the same. It is error prone, lots of copy&pasted code. We should have one place with declaration "this component supports these options, can pass those to that component" - and a component will understand its options specification from that json/yaml.
