John Ferlan 9fb14f75b3 docs: Update drivers page to link to storage.html
Rather than duplicate a list of storage pool backends on the
drivers.html page, let's just link directly to the storage driver
page similar to how the node device driver is done.

John Ferlan 642c06fd63 storage: Process storage pool capabilities
https://bugzilla.redhat.com/show_bug.cgi?id=1581670

During storage driver backend initialization, let's save
which backends are available in the storage pool capabilities.

In order to format those, we need add a connectGetCapabilities
processor to the storageHypervisorDriver. This allows a storage
connection, such as "storage:///system" to find the API and
format the results, such as:

  virsh -c storage:///system capabilities

  <capabilities>

    <pool>
      <enum name='type'>
        <value>dir</value>
        <value>fs</value>
        <value>netfs</value>
        <value>logical</value>
        <value>iscsi</value>
        <value>iscsi-direct</value>
        <value>scsi</value>
        <value>mpath</value>
        <value>disk</value>
        <value>rbd</value>

John Ferlan 850cfd75be storage: Fetch a unique key for vHBA/NPIV LUNs
https://bugzilla.redhat.com/show_bug.cgi?id=1657468

Commit be1bb6c95 changed the way volumes were stored from a forward
linked list to a hash table. In doing so, it required that each vol
object would have 3 unique values as keys into tables - key, name,
and path. Due to how vHBA/NPIV LUNs are created/used this resulted
in a failure to utilize all the LUN's found during processing.

During virStorageBackendSCSINewLun processing fetch the key (or
serial value) for NPIV LUN's using virStorageFileGetNPIVKey which
will formulate a more unique key based on the serial value and
the port for the LUN.

John Ferlan 5f9e211c93 util: Introduce virStorageFileGetNPIVKey
The vHBA/NPIV LUNs created via the udev processing of the
VPORT_CREATE command end up using the same serial value
as seen/generated by the /lib/udev/scsi_id as returned
during virStorageFileGetSCSIKey. Therefore, in order to
generate a unique enough key to be used when adding the
LUN as a volume during virStoragePoolObjAddVol a more
unique key needs to be generated for an NPIV volume.

The problem is illustrated by the following example, where
scsi_host5 is a vHBA used with the following LUNs:

$ lsscsi -tg
...
[5:0:4:0]    disk    fc:0x5006016844602198,0x101f00  /dev/sdh   /dev/sg23
[5:0:5:0]    disk    fc:0x5006016044602198,0x102000  /dev/sdi   /dev/sg24
...

Calling virStorageFileGetSCSIKey would return:

/lib/udev/scsi_id --device /dev/sdh --whitelisted --replace-whitespace /dev/sdh
350060160c460219850060160c4602198
/lib/udev/scsi_id --device /dev/sdh --whitelisted --replace-whitespace /dev/sdi
350060160c460219850060160c4602198

Note that althrough /dev/sdh and /dev/sdi are separate LUNs, they
end up with the same serial number used for the vol->key value.
When virStoragePoolFCRefreshThread calls virStoragePoolObjAddVol
the second LUN fails to be added with the following message
getting logged:

    virHashAddOrUpdateEntry:341 : internal error: Duplicate key

To resolve this, virStorageFileGetNPIVKey will use a similar call
sequence as virStorageFileGetSCSIKey, except that it will add the
"--export" option to the call. This results in more detailed output
which needs to be parsed in order to formulate a unique enough key
to be used. In order to be unique enough, the returned value will
concatenate the target port as returned in the "ID_TARGET_PORT"
field from the command to the "ID_SERIAL" value.
