Just like scylla-sstable, have a separate --help content for reach
action. The existing description is shortened and is demoted to summary:
this now only appears in the listing in the main description.
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
Which configures seastar to act more appropriate to a tool app. I.e.
don't act as if it owns the place, taking over all system resources.
These tools are often run on a developer machine, or even next to a
running scylla instance, we want them to be the least intrusive
possible.
Also use the new tool mode in the existing tools.

The infrastructure is now in place. Remove the proxy main of the tools,
and add appropriate `else if` statements to the executable switch in
main.cc. Also remove the tool applications from the `apps` list and add
their respective sources as dependencies to the main scylla executable.
With this, we now have all tool executables living inside the scylla
main one.
Rename actual main to `${tool_name}_main` and have a proxy main call it.
In the next patch we will get rid of these proxy mains and the tool
mains will be invoked from scylla's main, if the `argv[0]` matches their
name.
The main functions are included in a new `tools/entry_point.hh` header.
We want to use the pattern of having a command line flag for each
operation in more tools, so extract the logic which finds the selected
operation from the command line arguments into a function.
Eliminate not used includes and replace some more includes
with forward declarations where appropriate.

Just like scylla-sstable-index, scylla-types accepts types in (short)
cassandra class name notation. The mapping from the clq3 type names to
the class names is not straight-forward in all cases, so provide a link
to a table which lists the cassandra class name of all supported types
(and more).

C++20 introduced `contains` member functions for maps and sets for
checking whether an element is present in the collection. Previously
`count` function was often used in various ways.
`contains` does not only express the intend of the code better but also
does it in more unified way.
This commit replaces all the occurences of the `count` with the
`contains`.

Allow examining partition and clustering keys, by adding support for
full and prefix compound types. The members of the compound type are
specified by passing several types with --type on the command line.
Currently the available actions are documented in several different
places:
* code implementing them
* description
* documentation for --action
* error message that validates value for --action
This is guaranteed to result in incorrect, possibly self-contradicting
documentation. Resolve by generating all documentation from the handler
registry, which now also contains the description of the action.
Also have a separate flag for each action, instead of --action=$ACTION.
