Enhance devstack plugin
Add several features: - possibility to set any opt to any group - possibility to configure and enable any set of share backends Details: 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'. 3) Two default backends are used for compatibility with previous approach. Two defaults backends 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.

# ----------------------------------------------
|
||||
# 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'.
|
||||
#
|
||||
# 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.
