os/bluestore: fix deep-scrub operation againest disk silent errors

Say a object who has data caches, but in a while later, caches' underlying
physical device has silent disk erros accidentally, then caches and physical
data are not same. In such case, deep-scrub operation still tries to read
caches firstly and won't do crc checksum, then deep-scrub won't find such
data corruptions timely.

Here introduce a new flag 'CEPH_OSD_OP_FLAG_BYPASS_CLEAN_CACHE' which tells
deep-scrub to bypass object caches. Note that we only bypass cache who is in
STATE_CLEAN state. For STATE_WRITING caches, currently they are not written
to physical device, so deep-scrub operation can not read physical device and
can read these dirty caches safely. Once they are in STATE_CLEAN state(or not
added to bluestore cache), next round deep-scurb can check them correctly.

As to above discussions, I refactor BlueStore::BufferSpace::read sightly,
adding a new 'flags' argument, whose value will be 0 or:
     enum {
       BYPASS_CLEAN_CACHE = 0x1,     // bypass clean cache
     };

flags 0: normal read, do not bypass clean or dirty cache
flags BYPASS_CLEAN_CACHE: bypass clean cache, currently only for deep-scrube
                        operation

Test:
   I deliberately corrupt a object with cache, with this patch, deep-scrub
   can find data error very timely.

ceph_volume: Checking device validity at init time

When initializing the Device structure, it have to run is_valid() to
ensure the data structures (_is_valid & rejected_reasons) to be
populated accordingly to the device state.

ceph_volume: Rejecting locked devices

If we cannot open a block device in O_RDWR in exclusive mode, it means
someone is actually using it like a raw database or similar.

In that case, the device should be considered as unusable as OSDs will
not be in a position to use it.

ceph_volume: Reporting nr_requests

We are already reporting the rotational & scheduler of a disk device.
Reporting the nr_requests could be useful to get how many concurrent IOs
the device supports/reports.

That could help detecting badly detected/configured devices.

ceph_volume: Adding Device.is_valid()

A block device can be filtered-out/ignored because it have features that
doesn't match Ceph's expectations.

As of today, the current code was rejected removable devices but it was
pretty hidden from the user, and implicit in the get_devices() function.

This patch is creating a new is_valid() function to perform all the
rejection tests and returns if this device can be used in the Ceph
context or not.

If is_valid() is returning False, the 'rejected_reasons' list reports all
the reasons why that devices got rejected.
