vponomaryov 8c3c73ada6 Fix Cinder's NoValidHostFound errors 
Manila CI jobs create lots of shares and for Generic driver it means
lots of Cinder volumes. After merge of [1] to Cinder project, we started
having NoValidHostFound errors in Cinder logs, it changed default
oversubscription ratio to 1.0 from 20.0. But Manila CI requires it
be bigger than 1.0, so set it explicitly to Cinder's default value 20.0
that is used by all other driver but not LVM.

# Setting configuration file for manila services
# ----------------------------------------------
# 1) It is possible to set any custom opt to any config group using following:
# $ export MANILA_OPTGROUP_foo_bar=value
# where 'foo' is name of config group and 'bar' is name of option.
#
# 2) 'MANILA_CONFIGURE_GROUPS' contains list of config group names used to create
# config groups, but 'MANILA_ENABLED_BACKENDS' is used to set config groups as
# Manila share back ends. Both can be set like following:
# $ export MANILA_ENABLED_BACKENDS=foo,bar
# where 'foo' and 'bar' are names of config groups with opts for some share
# drivers. By default they are equal. Also be attentive, if you modify both,
# make sure 'MANILA_CONFIGURE_GROUPS' contains all values from
# 'MANILA_ENABLED_BACKENDS'.
# DEFAULT group is always defined, no need to specify it within 'MANILA_CONFIGURE_GROUPS'.
#
# 3) Two default backends are used for compatibility with previous approach.
# They have same configuration except name of backend. Both use generic driver.
# They can be enabled by adding values of following env vars:
# 'MANILA_BACKEND1_CONFIG_GROUP_NAME' and 'MANILA_BACKEND2_CONFIG_GROUP_NAME'
# to the env var 'MANILA_ENABLED_BACKENDS' or will be enabled
# if 'MANILA_ENABLED_BACKENDS' is empty.
#
# 4) 'CINDER_OVERSUBSCRIPTION_RATIO' - manila devstack-plugin env var that is
# useful for all share drivers that use Cinder. If it is set, then it will be
# applied for two Cinder options: 'max_over_subscription_ratio' and
# 'lvm_max_over_subscription_ratio'. Should be float. Example:
# CINDER_OVERSUBSCRIPTION_RATIO=20.0
# Defaults
