Release 0.7.1 version

This release fixes an issue with the keep_changes parameter, which results in enabling the functionality of keeping a history of changes in bird_conf even when it is set to false. This bug affects also the bird configuration for IPv6. We also fix a typo in the sanity check, which prevents the sanity check to catch missing Bird configuration for IPv6.

We now support floating numbers for check_timeout and check_interval parameters of service check. We also instruct systemd to restart the daemon upon failure. Last but not least, we clean up local_run.sh script.

Changelog:

• Update local_run.sh with latest config
• Don't handle bird configuration in local_run.sh
• Allow floating numbers for check_[timeout,interval]
• Instruct Systemd to restart daemon upon failure
• Use standard path rather our custom one
• Mention that prefix length is optional
• Fetch the correct parameter name
• Return boolean value instead of a string
• Update example anycast-healthchecker.conf
