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
Replace stdx::optional and stdx::string_view with the C++ std
counterparts.
Some instances of boost::variant were also replaced with std::variant,
namely those that called seastar::visit.

Cassandra 3.10 added the `duration` type [1], intended to manipulate date-time
values with offsets (for example, `now() - 2y3h`).
The full implementation of the `duration` type in Scylla requires support
for version 5 of the binary protocol, which is not yet available.
In the meantime, this patch patch adds the implementation of the underlying type
for the eventual `duration` type. Included is also the ported test suite from
the reference implementation and additional tests.
Related to #2240.
