Block device spins forever when status == creating

[Joshua Harlow]

The current code seems to spin forever (and basically absorb a greenthread) when the volume api has said the status is still in creating instead of stopping after a given X number of attempts.

    Limit the checks for block device becoming available.

    Instead of previously looping potentially forever for a block
    device mapping to become created from the volume api, basically
    blocking a greenthread until this happens we now will have a number
    of attempts (defaulting to 10) that we will wait for the volume api
    to create said block device mapping (or error out).

    Fixes bug 1162064
