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 method sits in dist.loader, but really belongs to util/ as it
just works on an "abstract" path and doesn't need to know what this
path is about. Another sign of layering violation is the inclusion
of dist.loader code into util/ stuf.

Currently, the `directories` class is used exclusively during
initialization, in the main() function. This commit refactors this class
so that it is possible to use it to initialize directories much later
after startup.
The intent of this change is to make it possible for hints manager to
create directories for hints lazily. Currently, when Scylla is booted
with hinted handoff disabled, the `hints_directory` config parameter is
ignored and directories for hints are neither created nor verified.
Because we would like to preserve this behavior and introduce
possibility to switch hinted handoff on in runtime, the hints
directories will have to be created lazily the first time hinted handoff
is enabled.
The list of paths that should be touch-and-locked is already
at hands, this shortens the code and makes it slightly faster
(in theory).

In order not to pollute the root dir place the code in
utils/ directory, "utils" namespace.
While doing this -- move the touch_and_lock from the
class declaration.
