The following command had been executed to get the
list of headers that did not contain '#pragma once':
'grep -rnw . -e "#pragma once" --include *.hh -L'
This change adds missing include guard to headers
that did not contain any guard.

Soon, we will want to convert mutation fragments into json inside the
scylla codebase, not just in tools. To avoid scylla-core code having to
include tools/ (and link against it), move the low-level json utilities
into mutation/.
The values of cells are potentially very large and thus, when presenting
row content as json in SELECT * FROM MUTATION_FRAGMENTS($table) queries,
we want to separate metadata and cell values into separate columns, so
users can opt out from the potentially big values being included too.
To support this use-case, write(row) and its downstream write methods
get a new `include_value` flag, which defaults to true. When set to
false, cell values will not be included in the json output. At the same
time, new methods are added to convert only cell values of a row to
json.
1) mutation_partition_json_writer - containing all the low level
utilities for converting sub-fragment level mutation components (such
as rows, tombstones, etc.) and their components into json;
2) mutation_fragment_stream_json_writer - containing all the high level
logic for converting mutation fragment streams to json;
The latter using the former behind the scenes. The goal is to enable
reuse of converting mutation-fragments into json, without being forced
to work around differences in how the mutation fragments are reprenented
in json, on the higher level.
Schema related files are moved there. This excludes schema files that
also interact with mutations, because the mutation module depends on
the schema. Those files will have to go into a separate module.
