When generating a default config instead of using a canned value like "eth0", hypd will isntead look at what interfaces the system has and make a best guess based on progressively narrowing filters.

If refreshtime is specified, instead the client running as a one-shot command, it will instead run persistently and perform a new authentic knock sequence each specified time in minutes.

fix incorrect logic in rotateSequence

This was introduced in the previous few commits when adding support for multiple secrets in knockd. The logic to push and pop entries from the knockSequences slice needed to be adjusted to cound for the number of secrets that are loaded by hypd.

continuous-integration/drone/push Build is failing
This allows you to generate more than one pre-shared secret on the knock daemon so that you can distribute the secret and control revocation at a more granular level. Each additional secret creates one more concurrent authentic knock sequence.
