Now after changing Context.h 488 modules will be recompiled instead of 582.

Remove experimental_use_processors setting, part 1.

* Move some code outside dbms/src folder

Mass rename: AccessRightsContext -> ContextAccess, QuotaContext -> EnabledQuota, RoleContext -> EnabledRoles, and so on.

With Processors max_distributed_connections does not used anymore, since
it always uses not more then max_threads (see

QueryPipeline::execute()/PipelineExecutor::execute())

So just use QueryPipeline::getNumThreads(), that takes
max_distributed_connections into account.

Set X-ClickHouse-Timezone HTTP Response header in the executeQuery() callback
