1. What is the problem?
The oslo.config support a 'mutable' parameter to Opts.
This is only respected when the new method mutate_config_files
is called instead of reload_config_files.so we need to enable
mutable config in tricircle.
2. What is the solution to the problem?
Depend on the two path in oslo.config which are
Icec3e664f3fe72614e373b2938e8dee53cf8bc5e and
I1e7a69de169cc85f4c09954b2f46ce2da7106d90 made the Tricircle
have the ability to mutable config.
3. What the features to be implemented in the Tricircle to realize the solution?
Further patches will be needed to make select config options be marked as
mutable. This change enables support for oslo provided config options
to be updated via SIGHUP such as log level.
