feat(ui): allow to send multiple queries to dashboard

[sranka]

Closes #5703

Briefly describe your proposed changes:

1. Use query from an active tab OOTB
2. Let the user choose whether to send the active query, or all queries

What was the problem?

• only the query from the first query tab was used, without letting the user know
• it was not clear what is exactly being sent to a dashboard

What was the solution?

• active tab query is used, it is a default option
• the user can choose whether to send only an active query or all queries

• CHANGELOG.md updated with a link to the PR (not the Issue)
• Well-formatted commit messages
• Rebased/mergeable
• Tests pass

@timhallinflux I let the user choose what to add (Active Query or All queries) ... does it meet the expectation of the reported issue?
