Do not check *optimize_skip_unused_shards_nesting w/o *optimize_skip_unused_shards
...
This will avoid supperior log message in case of
*optimize_skip_unused_shards_nesting already disables it.
And also it is logical.

Add settings to control nesting level for shards skipping optimization
...
- optimize_skip_unused_shards_nesting (allows control nesting level for
shards skipping optimization)
- force_skip_optimize_shards_nesting (allows control nesting level for
checking was shards skipped or not)
- deprecates force_skip_optimize_shards_no_nested

optimize_skip_unused_shards=2 will disable it for nested distributed queries
...
P.S. Looks like settings can be converted between SettingUInt64 and
SettingBool without breaking binary protocol.
FWIW maybe it is a good idea to change the semantics of the settings as
follow (but I guess that changing semantic is not a good idea, better to
add new settings and deprecate old ones):
- optimize_skip_unused_shards -- accept nesting level on which the
optimization will work
- force_skip_optimize_shards_nesting -- accept nesting level on which
the optimization will work
