Eoghan Glynn dd6975eadc Fix hash-bang directive in nova_create_flavors.sh
The script employs bash-isms, so the directive to use the
Bourne shell causes some predictable failures:

  nova_create_flavors.sh: [[: not found

... etc.

# Create additional nova instance types (flavors)
# to map to the AWS instance types we have in the templates
# Default nova install (via tools/openstack) gives this:
# +----+-----------+-----------+------+-----------+------+-------+-------------+
# | ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor |
# +----+-----------+-----------+------+-----------+------+-------+-------------+
# | 1 | m1.tiny | 512 | 0 | 0 | | 1 | 1.0 |
# | 2 | m1.small | 2048 | 10 | 20 | | 1 | 1.0 |
# | 3 | m1.medium | 4096 | 10 | 40 | | 2 | 1.0 |
# | 4 | m1.large | 8192 | 10 | 80 | | 4 | 1.0 |
# | 5 | m1.xlarge | 16384 | 10 | 160 | | 8 | 1.0 |
# +----+-----------+-----------+------+-----------+------+-------+-------------+
# Templates define these as valid
# "t1.micro" : { "Arch" : "32" },
# "m1.small" : { "Arch" : "32" },
# "m1.large" : { "Arch" : "64" },
# "m1.xlarge" : { "Arch" : "64" },
# "m2.xlarge" : { "Arch" : "64" },
# "m2.2xlarge" : { "Arch" : "64" },
# "m2.4xlarge" : { "Arch" : "64" },
# "c1.medium" : { "Arch" : "32" },
# "c1.xlarge" : { "Arch" : "64" },
# "cc1.4xlarge" : { "Arch" : "64" }
# So for development purposes, we create all flavors, but with a maximum of
# 2vcpus, 10G disk and 2G RAM (since we're all running on laptops..)
# Nova rate limits actions so we need retry/sleep logic to avoid
# spurious failures when doing sequential operations
# we also sleep after every operation otherwise rate-limiting will definitely
# cause lots of failures
