Matt Riedemann d0264372fe Fix vmware quota extra specs reno formatting
The bullets shows up as separate features when looking
at all release notes together, which is confusing. We
should document these as sub-bullets under a common
block of text for the overall feature.

For the VMware driver, the flavor extra specs for quotas has been extended
to support:
- quota:cpu_limit - The cpu of a virtual machine will not
exceed this limit, even if there are available resources. This is
typically used to ensure a consistent performance of virtual machines
independent of available resources. Units are MHz.
- quota:cpu_reservation - guaranteed minimum reservation (MHz)
- quota:cpu_shares_level - the allocation level. This can be
'custom', 'high', 'normal' or 'low'.
- quota:cpu_shares_share - in the event that 'custom' is used,
this is the number of shares.
- quota:memory_limit - The memory utilization of a virtual
machine will not exceed this limit, even if there are available
resources. This is typically used to ensure a consistent performance of
virtual machines independent of available resources. Units are MB.
- quota:memory_reservation - guaranteed minimum reservation (MB)
- quota:memory_shares_level - the allocation level. This can be
'custom', 'high', 'normal' or 'low'.
- quota:memory_shares_share - in the event that 'custom' is used,
this is the number of shares.
- quota:disk_io_limit - The I/O utilization of a virtual machine
will not exceed this limit. The unit is number of I/O per second.
- quota:disk_io_reservation - Reservation control is used to
provide guaranteed allocation in terms of IOPS
- quota:disk_io_shares_level - the allocation level. This can be
'custom', 'high', 'normal' or 'low'.
- quota:disk_io_shares_share - in the event that 'custom' is used,
this is the number of shares.
- quota:vif_limit - The bandwidth limit for the virtual network
adapter. The utilization of the virtual network adapter will not exceed
this limit, even if there are available resources. Units in Mbits/sec.
- quota:vif_reservation - Amount of network bandwidth that is
guaranteed to the virtual network adapter. If utilization is less than
reservation, the resource can be used by other virtual network adapters.
Reservation is not allowed to exceed the value of limit if limit is set.
Units in Mbits/sec.
- quota:vif_shares_level - the allocation level. This can be
'custom', 'high', 'normal' or 'low'.
- quota:vif_shares_share - in the event that 'custom' is used,
this is the number of shares.
