We have API for getting pending compaction tasks both in column
family and compaction manager. Column family is already returning
pending tasks properly.
Compaction manager's one is used by 'nodetool compactionstats', and
was returning a value which doesn't reflect pending compaction.

- Instead of keeping separate booleans introduce a trace_state_props_set enum_set and
pass it around instead of separate booleans.
- Change the trace_info to hold this value in addition to write_on_close. Initialize
a corresponding bit in an enum_set based on a write_on_close value in a trace_info
constructor for a backward compatibility.
- Separate a trace_state constructor into two:
- For a primary session object.
- For a secondary session object.

Normally, the check version should start and stop with the scylla-server
service.
If it fails to find scylla server, there is no need to check the
version, nor to report it, so it can stop silently.

Size estimates for a particular column family are recorded every 5
minutes. However, when a user calls the describe_splits(_ex) verbs,
they may want to see estimates for a recently created and updated
column family; this is legitimate and common in testing. However, a
client may also call describe_splits(_ex) very frequently and
recording the estimates on every call is wasteful and, worse, can
cause clients to give up. This patch fixes this by only recording
estimates if the first attempt to query them produces no results.

After state_processor().process_state() returns proceed::no the upper
layer should have a chance to act before more data is pushed to the
consumer. This means that in case of proceed::no verify_end_state()
should not be called immediately since it may invoke

This patch uses the clustering bounds comparator to correctly detect
wrap around of a clustering range. This fixes a manifestation of #1446,
introduced by b1f9688432, where a query
such as select * from cf where k = 0x00 and c0 = 0x02 and c1 > 0x02
would result in a range containing a clustering key and a prefix,
incorrectly ordered by the prefix equality or lexicographical
comparators.

As part of the move to unwrap ranges, don't generate wrapping ranges from
thrift. A little extra motivation is to avoid the need for the solution
to #1573 to be able to handle wrapping ranges.
This patch may also be fixing a bug in that the range (token, token] was
previously translated as (-inf, +inf), while now it is translated as
{(token, +inf), (-inf, token]}; the new translation respects ordering
better.

Deserialization code is going to use a proxy object that will be casted
to either bytes or bytes_ostream depending on the demand. It cannot be
casted directly to bytes_view though as it won't extend the lifetime of
the buffer appropriately. The simples solution is just to add overloads
that accept const bytes&.
