Every time db/config.hh is modified (e.g., to add a new configuration
option), 110 source files need to be recompiled. Many of those 110 didn't
really care about configuration options, and just got the dependency
accidentally by including some other header file.
In this patch, I remove the include of "db/config.hh" from all header
files. It is only needed in source files - and header files only
need forward declarations. In some cases, source files were missing
certain includes which they got incidentally from db/config.hh, so I
had to add these includes explicitly.
After this patch, the number of source files that get recompiled after a
change to db/config.hh goes down from 110 to 45.
It also means that 65 source files now compile faster because they don't
include db/config.hh and whatever it included.
Additionally, this patch also eliminates a few unnecessary inclusions
of database.hh in other header files, which can use a forward declaration
or database_fwd.hh. Some of the source files including one of those
header files relied on one of the many header files brought in by
database.hh, so we need to include those explicitly.
In view_update_generator.hh something interesting happened - it *needs*
database.hh because of code in the header file, but only included
database_fwd.hh, and the only reason this worked was that the files
including view_update_generator.hh already happened to unnecessarily
include database.hh. So we fix that too.

The only place in redis that needs migration manager is the
::init method that's called on start. It's possible to pass
the migration manager as an argument.

storage_proxy.hh is huge and includes many headers itself, so
remove its inclusions from headers and re-add smaller headers
where needed (and storage_proxy.hh itself in source files that
need it).
Ref #1.
The cql_server and redis_server share the same ancestor of do_accepts().
Let's pull up the cql_server version of do_accept() (that has more
functionality) to generic_server::server and use it in the redis_server
too.
Pull up the cql_server process() to base class and convert redis_server
to use it.
Please note that this fixes EPIPE and connection reset issue in the
Redis server, which was fixed in the CQL server in commit 1a8630e6a
("transport: silence "broken pipe" and "connection reset by peer"
errors").
The cql_server and redis_server both have the same "_stopped" and
"_connections_list" member variables. Pull them up to the
generic_server::server base class.
The cql_server and redis_server classes have a maybe_idle() method,
which sets the _all_connections_stopped promise if server wants to stop
and can be stopped. Pull up the duplicated code to
generic_server::server class.
Both cql_server::connection and redis_server::connection inherit
boost::intrusive::list_base_hook<>, so let's pull up that to the
generic_server::connection class that both inherit.
This patch moves the duplicated connection::shutdown() method to to a
new generic_server::connection base class that is now inherited by
cql_server and redis_server.
This pull request removes seastar namespace imports from the header
files. There are some additional cleanups to make that easier and to
remove some commented out code.

There are two types of numerical parameter in redis protocol:
- *[0-9]+ defined array size
- $[0-9]+ defined string size
Currently, array size is stored to args_count, and string size is
stored to _arg_size / _size_left.
It's bit hard to understand since both uses same word "arg(s)", let's
rename string size variables to _bytes_count / _bytes_left.
If the message is larger than current buffer size, we need to consume
more data until we reach to tail of the message.
To do so, we need to return nullptr when it's not on the tail.
Fixes#7273
Since we haven't implemented parse error on redis protocol parser,
reply message is broken at parse error.
Implemented parse error, reply error message correctly.

It looks like the history of the flag begins in Cassandra's
https://issues.apache.org/jira/browse/CASSANDRA-7327 where it is
introduced to speedup tests by not needing to start the gossiper.
The thing is we always start gossiper in our cql tests, so the flag only
introduce noise. And, of course, since we want to move schema to use raft
it goes against the nature of the raft to be able to apply modification only
locally, so we better get rid of the capability ASAP.
Tests: units(dev, debug)

If we start a sharded<> object, then proceed to do potentially
exceptional stuff, we should destroy it on said exception.
Otherwise, the exception propagation will abort on RAII
destruction of the sharded<>. And we get no exception logging.
get() the latest token_metadata_ptr from the
shared_token_metadata before each use.
expose get_token_metadata_ptr() rather than get_token_metadata()
so that caller can keep it across continuations.
