Similar to gdb's "thread apply all". Executes given command in the
context of each seastar thread.
For example to print backtrace of all threads:
scylla thread apply-all bt
If a composite is not a compound, then it doesn't carry a length
prefix where static information is encoded. In its absence, a
non-compound composite can never be static.

This patch ensures we fail when creating a mixed column family, either
when adding columns to a dynamic CF through updated_column_family() or
when adding a dynamic column upon insertion.

This patch implements the describe_splits_ex verbs by querying the
size_estimates system table for all the estimates in the specified
token range.
If the keys_per_split argument is bigger then the
estimated partitions count, then we merge ranges until keys_per_split
is met. Note that the tokens can't be split any further,
keys_per_split might be less than the reported number of keys in one
or more ranges.

The query_size_estimates() function queries the size_estimates system
table for a given keyspace and table, filtering out the token ranges
according to the specified tokens.

This patch fixes stop() by checking if the current CPU instead of
whether the service is active (which it won't be at the time stop() is
called).

This patch makes range_estimates a proper struct, where tokens are
represented as dht::tokens rather than dht::ring_position*.
We also pass other arguments to update_ and clear_size_estimates by
copy, since one will already be required.

Cassandra 1.x clusters often use RandomPartitioner. Supporting
RandomPartitioner will allow easier migration to Scylla
Tests are added to make sure scylla generates the same token as
Cassandra does for the same partition key.

This patch converts an exceptions::invalid_request_exception
into a Thrift InvalidRequestException instead of into a generic one.
This makes TitanDB work correctly, which expects an
InvalidRequestException when setting a non-existent keyspace.

We use ::abs(), which has an int parameter, on long arguments, resulting
in incorrect results.
Switch to std::abs() instead, which has the correct overloads.

A seastar::value_of() lambda used in a trace point was doing the unthinkable:
it called std::move() on a value captured by reference. Not only it compiled(!!!)
but it also actually std::move()ed the shared_ptr before it was used in a make_result()
which naturally caused a SIGSEG crash.
