Update git submodules
* Update tripleo-ansible from branch 'master' to 25a42e3a75db042695d4875c26e0a326c27c90f6 - Merge "Define role specific defaults for growvols_args" - Define role specific defaults for growvols_args The Controller role will sometimes include swift object storage, and the ObjectStorage role always will. This means unless the /srv volume is grown it will be too small for swift to store any useful amount of data. The node provision tool has no knowledge of the specific services deployed in a role, so it can only set growvols_args default based on the role name. This change makes the default growvols_args role-aware so that Controller and ObjectStorage roles grow /srv by enough to be useful. The documentation will encourage the deployer to consider actual /var and /srv storage requirements (especially for the Controller role) and setting custom growvols_args to reflect that. It is impossible to choose defaults which meet all scenarios because there are 3 unknowns (workload requirements for /var and /srv, and the size of the node primary disk) so some discusson of Controller requirements especially is encouraged. If /srv or /var are deployed with insufficient space the deployer can always add a second disk and expand the LVM volume into that, so there is a mitigation option.
