parse_duration() doesn't understand seconds

[meejah]

User ​https://github.com/sgerodes on GitHub? reports:

configuring seconds in override_lease_duration previously resulted in errors due to missing elif statement in the parse_duration function

This configuration

[storage]
expire.enabled = True
expire.mode = age
expire.override_lease_duration = 100000s

Results in this error

Unknown error, here's the traceback:
