Tomasz Zawadzki 29bd502046 lib/blob: add invalid flag for extent table
With recent changes to extent on-disk metadata format,
new format (Extent Pages) is not backwards compatible.
Meanwhile old format (Extent RLE) is backwards
compatible with older SPDK applications.

Summing up:
Blobstore created pre SPDK 20.01 can only use Extent RLE.
Blobstore created starting with SPDK 20.01 can use both,
Extent Pages and Extent RLE specified by use_extent_table opts.

When use_extent_table is set to true, invalid flag for it is set.
SPDK application pre 20.01, will not load such blob.
