[gardener-extension-provider-openstack]

Most notable changes

• [OPERATOR] The logging configuration has been adapted to cater with Loki which was introduced as part of gardener/gardener#2515. If an older version of this extension is used with a Gardener version >= v1.8 and the Logging feature gate is enabled then the fluent-bit matcher won't catch the log anymore (resulting in the logs being collected, but not nicely parsed and instead displayed in nested JSON). It is recommended update to at least this extension version when Gardener >= v1.8 is used and the Logging feature gate is enabled. (#115, @Kristian-ZH)
• [OPERATOR] Until now provider-openstack was maintaining a Terraform configuration which is both v0.12 and v0.11 compatible. The Terraform configuration is now adapted to the new Terraform language which makes it Terraform v0.11 incompatible. (#112, @ialidzhikov)

Improvements

• [USER] StorageClasses now allow for expansion of PVCs. (#119, @mvladev)

• [USER] The floating pool subnet which a router should be attached to can now be specified. (#92, @dkistner)
• [OPERATOR] The default webhook server port is now changed to 10250. (#125, @stoyanr)
• [OPERATOR] Worker extension allows configuring following parameters on machine-deployment: drainTimeout, creationTimeout, healthTimeout, maxEvictRetries, nodeConditions. (#124, @hardikdr)
• [OPERATOR] A bug has been fixed, that caused the Infrastructure deletion to be blocked forever in case there are already running terraformer Pods. (#113, @timebertt)
