ZhongShengping 6577331930 Add manage_backend_package parameter
Adds the manage_backend_package parameter that is sent to the
oslo::cache class that determines if we should install the backend
python library for caching.

The default value is not changed and defaults to true same as the
oslo::cache class does.

# Class nova::cache
#
# nova cache configuration
#
# == parameters
#
# [*config_prefix*]
# (Optional) Prefix for building the configuration dictionary for
# the cache region. This should not need to be changed unless there
# is another dogpile.cache region with the same configuration name.
# (string value)
# Defaults to $::os_service_default
#
# [*expiration_time*]
# (Optional) Default TTL, in seconds, for any cached item in the
# dogpile.cache region. This applies to any cached method that
# doesn't have an explicit cache expiration time defined for it.
# (integer value)
# Defaults to $::os_service_default
#
# [*backend*]
# (Optional) Dogpile.cache backend module. It is recommended that
# Memcache with pooling (oslo_cache.memcache_pool) or Redis
# (dogpile.cache.redis) be used in production deployments. (string value)
# Defaults to $::os_service_default
#
# [*backend_argument*]
# (Optional) Arguments supplied to the backend module. Specify this option
# once per argument to be passed to the dogpile.cache backend.
# Example format: "<argname>:<value>". (list value)
# Defaults to $::os_service_default
#
# [*proxies*]
# (Optional) Proxy classes to import that will affect the way the
# dogpile.cache backend functions. See the dogpile.cache documentation on
# changing-backend-behavior. (list value)
# Defaults to $::os_service_default
#
# [*enabled*]
# (Optional) Global toggle for caching. (boolean value)
# Defaults to $::os_service_default
#
# [*debug_cache_backend*]
# (Optional) Extra debugging from the cache backend (cache keys,
# get/set/delete/etc calls). This is only really useful if you need
# to see the specific cache-backend get/set/delete calls with the keys/values.
# Typically this should be left set to false. (boolean value)
# Defaults to $::os_service_default
#
# [*memcache_servers*]
# (Optional) Memcache servers in the format of "host:port".
# (dogpile.cache.memcache and oslo_cache.memcache_pool backends only).
# (list value)
# Defaults to $::os_service_default
#
# [*memcache_dead_retry*]
# (Optional) Number of seconds memcached server is considered dead before
# it is tried again. (dogpile.cache.memcache and oslo_cache.memcache_pool
# backends only). (integer value)
# Defaults to $::os_service_default
#
# [*memcache_socket_timeout*]
# (Optional) Timeout in seconds for every call to a server.
# (dogpile.cache.memcache and oslo_cache.memcache_pool backends only).
# (integer value)
# Defaults to $::os_service_default
#
# [*memcache_pool_maxsize*]
# (Optional) Max total number of open connections to every memcached server.
# (oslo_cache.memcache_pool backend only). (integer value)
# Defaults to $::os_service_default
#
# [*memcache_pool_unused_timeout*]
# (Optional) Number of seconds a connection to memcached is held unused
# in the pool before it is closed. (oslo_cache.memcache_pool backend only)
# (integer value)
# Defaults to $::os_service_default
#
# [*memcache_pool_connection_get_timeout*]
# (Optional) Number of seconds that an operation will wait to get a memcache
# client connection. (integer value)
# Defaults to $::os_service_default
#
# [*manage_backend_package*]
# (Optional) (Optional) Whether to install the backend package for the cache.
# Defaults to true
