refactor(QueryObject): decouple from queryContext and clean code

[ofekisr]

Background

When we have worked on #16991 we wanted to test the new functionalities in concrete and accurate unittest.
All chartData flows and its components are too couple to superset so it is impossible to create unittests.
The flows are not testable and so many components do not meet the very important principle SRP and the code became so dirty

So I've started to refactor it (#17344 ) but many changes were added and it was hard to review so I decided to split those changes into small PRs so will be easier to follow

This is the seventh PR in a sequence of PRs to meet these
The next PR is #17466

PR description

as written, decouple QueryObject from its parent and some clean code (method extractions)

Test plans

There are no logic changes, so new tests are not required

Previous PRs

1. refactor(ChartData): move ChartDataResult enums to common #17399
2. refactor(ChartData): move chart_data_apis from ChartRestApi ChartDataRestApi #17400
3. refactor(ChartDataCommand): separate loading query_context form cache into different module #17405
4. refactor(TestChartApi): move chart data api tests into TestChartDataApi #17407
5. refactor(ChartDataCommand): into two separate commands #17425
6. refactor(ChartDataCommand): remove create queryContext command's responsibly  #17461
