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
Although std::map::find is not guaranteed to be noexcept
it depends on the comperator used and in this case comparing application_state
is noexcept. Therefore, we can safely mark get_application_state_ptr noexcept.
is_cql_ready depends on get_application_state_ptr and otherwise
handles an exceptions boost::lexical_cast so it can be marked
noexcept as well.

Now that get_next_version() is noexcept,
update_heart_beat can be noexcept too.
All others are trivially noexcept.

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.
Scylla now requires GCC 8 to compile.
