Allow offline bootstrapping of cabal-install

This ports to cabal-install the offline bootstrapping logic which was
introduced for Hadrian in GHC MR !6315.

This adds a "fetch" command to the bootstrap script, which fetches
all the dependency tarballs from Hackage, to be used in an offline
build. See bootstrap/README.md for further information.

* pass some haddock flags to dependencies

* add tests

* add changelog

* fix whitespace

* fix test on MacOS

Revert "Revert "Turn off DeterministicTrivial test (see #8356)""

It still hits us. All updates are over on #8356.

This reverts commit c68ed017.

Fixed changelog entry for haddock-package command

Make validate.sh show the output of cabal-plan

Closes #8440

* [ mergify ] fix condition of 'merge delay passed' label

Add the same conditions that we apply for the last stage of PR: 2 approvers and merge-me label. Otherwise, we get a lot of old PRs as well as some current ones getting the label prematurely.

* Remove warning on option -threaded when building libraries

Fixes #8431. Accompanied by option -flink-rts, option -threaded defines
the flavour of the ghc RTS library the built library will be linked
against. Note that bare ghc does not warn when option -threaded is used
for building a library either.

* Cabal no longer warns on -threaded option when building libraries

Note that this commit modifies regression check for issue #774.

* A small changelog was added

The proper way to print stuff is not a naive `putStrLn`, but using one
of the methods from Distribution.Simple.Utils, like `notice verbosity`.

Also allow latest aeson, network-wait, optparse-applicative in cabal-testsuite.
