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.

In Scylla we have three implementations of vector-like structures
std::vector, utils::chunked_vector and utils::small_vector. Which one is
used is largerly an implementation detail and all should be serialised
by the IDL infrastructure in exactly the same way. To make sure that
it's indeed the case let's make them share the serialiser
implementation.
deserialized_bytes_proxy assumes that the provided input stream has
iterator_type that represents the iterator pointing to the next
fragment of the fragmented underlying buffyer. This makes little sense
if the input stream is a contiguous one (i.e.
simple_memory_input_stream) so let's not make such assumptions.
Serialization for FragmentRange classes is added to serialization
suite. It first serializes total length to a 32bit field and then
writes each fragment to output.

Helps paged queries consistently hit the same replicas for each
subsequent page. Replicas that already served a page will keep the
readers used for filling it around in a cache. Subsequent page request
hitting the same replicas can reuse these readers to fill the pages
avoiding the work of creating these readers from scratch on every page.
In a mixed cluster older coordinators will ignore this value.
The value of last_replicas may change between pages as nodes may become
available/unavailable or the coordinator may decide to send the read
requests to different replicas at its discretion.
Replicas are identified by an opaque uuid which should only make sense
to the storage-proxy.

This patch adds a stub support for boost::variant. Currently variant are
not serialized, this is added just so non stub classes will be able to
compile.
deserialize for chrono::time_point and deserializer for chrono::duration
unknown variant:
Planning for situations where variant could be expanded, there may be
situation that a variant will return an unknown value.
In those cases the data and index will be paseed to the reader, that
can decide what to do with it.

Array of integral types on little endian machine can be memcpyed into/out
of a buffer instead of serialized/deserialized element by element.

Not all the idls are used by the messaging service, this patch removes
the auto-generated single include file that holds all the files and
replaes it with individual include of the generated fiels.
The patch does the following:
* It removes from the auto-generated inc file and clean the configure.py
from it.
* It places an explicit include for each generated file in
messaging_serivce.
* It add dependency of the generated code in the idl-compiler, so a
change in the compiler will trigger recreation of the generated files.

This patch adds the serializer and serializer_imple files. They holds
the functions that are not auto generated: primitives and templates (map
and vector) It also holds the include to the auto-generated code.
