fcb8d040e8 treewide: use Software Package Data Exchange (SPDX) license identifiers
Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.

Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.

The changes we applied mechanically with a script, except to
licenses/README.md.

Closes #9937

46f0354cdb redis: pass request as a reference
This patch change the way the request object is passed,
using a reference instead of temporaries.

'exists' test is passing in debug mode, whereas it was
always failing before.

Fixes #7261 by ensuring request object is alive for all commands
during the whole request duration.

bd82b4fc03 redis: remove commands classes
This patch is a proposal for the removal of the redis
classes describing the commands. 'prepare' and 'execute'
class functions have been merged into a function with
the name of the command.

Note: 'command_factory' still needs to be simplified.

63a1a4cbb9 redis: add hgetall and hdel commands
This patch adds support for 2 hash commands HDEL and HGETALL.

Internally it introduces the hashes_result_builder class to
read hashes and stored them in a std::map.

Other changes:
  - one exception return string was fixed
  - tests now use pytest.raises

19683d04c6 redis: add hget and hset commands
hget and hset commands using hashes internally, thus
they are not using the existing write_strings() function.

Limitations:
 - hset only supports 3 params, instead of multiple field/value
list that is available in official redis-server.
 - hset should return 0 when the key and field already exists,
but I am not sure it's possible to retrieve this information
without doing read-before-write, which would not be atomic.

I factorized a bit the query_* functions to reduce duplication, but
I am not 100% sure of the naming, it may still be a bit confusing
between the schema used (strings, hashes) and the returned format
(currently only string but array should come later with hgetall).
