Bootstrap clingo from binaries (#22720)

Browse source 
* Bootstrap clingo from binaries

* Move information on clingo binaries to a JSON file

* Add support to bootstrap on Cray

Bootstrapping on Cray requires, at the moment, to
swap the platform when looking for binaries - due
to #22800.

* Add SHA256 verification for bootstrapped software

Use sha256 verification for binaries necessary to bootstrap
the concretizer and gpg for signature verification

* patchelf: use Spec._old_concretize() to bootstrap

As noted in #24450 we may happen to need the
concretizer when bootstrapping clingo. In that case
only the old concretizer is available.

* Add a schema for bootstrapping methods

Two fields have been added to bootstrap.yaml:
  "sources" which lists the methods available for
       bootstrapping software
  "trusted" which records if a source is trusted or not

A subcommand has been added to "spack bootstrap" to list
the sources currently available.

* Methods used for bootstrapping are configurable from bootstrap:sources

The function that tries to ensure a given Python module
is importable now tries bootstrapping methods in the same
order as they are defined in `bootstrap.yaml`

* Permit to trust/untrust bootstrapping methods

* Add binary tests for MacOS, Ubuntu

* Add documentation

* Add a note on bash

Spack has the following minimum system requirements, which are assumed to
be present on the machine where Spack is run:
#. Python 2 (2.6 or 2.7) or 3 (3.5 - 3.9) to run Spack
#. A C/C++ compiler for building and the ``bash`` shell for Spack's compiler
wrapper
#. The ``make`` executable for building
#. The ``tar``, ``gzip``, ``unzip``, ``bzip2``, ``xz`` and optionally ``zstd``
executables for extracting source code
#. The ``patch`` command to apply patches
#. The ``git`` and ``curl`` commands for fetching
#. If using the ``gpg`` subcommand, ``gnupg2`` is required

^^^^^^^^^^^^^^^^^^^^
Bootstrapping clingo
^^^^^^^^^^^^^^^^^^^^
Spack supports using ``clingo`` as an external solver to compute which software
needs to be installed. The default configuration allows Spack to install
``clingo`` from a public buildcache, created by a Github Action workflow. In this
case the bootstrapping procedure is transparent to the user, except for a
slightly long waiting time on the first concretization of a spec:
.. code-block:: console
$ spack find -b
==> Showing internal bootstrap store at "/home/spack/.spack/bootstrap/store"
==> 0 installed packages
$ time spack solve zlib
==> Best of 2 considered solutions.
==> Optimization Criteria:

2 version weight 0
3 number of non-default variants (roots) 0
4 multi-valued variants 0
5 preferred providers for roots 0
6 number of non-default variants (non-roots) 0
7 preferred providers (non-roots) 0
8 compiler mismatches 0
9 version badness 0
10 count of non-root multi-valued variants 0

real 0m30,618s
user 0m27,278s
sys 0m1,549s
After this command you'll see that ``clingo`` has been installed for Spack's own use:
.. code-block:: console
$ spack find -b
==> Showing internal bootstrap store at "/home/spack/.spack/bootstrap/store"
==> 2 installed packages
-- linux-rhel5-x86_64 / gcc@9.3.0 -------------------------------
clingo-bootstrap@spack python@3.6
Subsequent calls to the concretizer will then be much faster:
.. code-block:: console
$ time spack solve zlib
[ ... ]
real 0m1,222s
user 0m1,146s
sys 0m0,059s
If for security or for other reasons you don't want to or can't install precompiled
binaries, Spack can fall-back to bootstrap ``clingo`` from source files. To forbid
Spack from retrieving binaries from the bootstrapping buildcache, the following
command must be given:
.. code-block:: console
$ spack bootstrap untrust github-actions
==> "github-actions" is now untrusted and will not be used for bootstrapping
since an "untrusted" way of bootstrapping software will not be considered
by Spack. You can verify the new settings are effective with:
.. code-block:: console
$ spack bootstrap list

Type: buildcache

Specs built from sources by Spack. May take a long time.
When bootstrapping from sources, Spack requires a compiler with support
for C++14 (GCC on ``linux``, Apple Clang on ``darwin``) and static C++
standard libraries on ``linux``. Spack will build the required software
on the first request to concretize a spec:
.. code-block:: console

If you want to speed-up bootstrapping ``clingo`` from sources, you may try to
search for ``cmake`` and ``bison`` on your system:

under the ``${HOME}/.spack`` directory. The software installed there can be queried with:
.. code-block:: console
$ spack find --bootstrap
