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
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

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).
