Enhancement interface that installer plugins can implement in order to
provide functionality that configures the software to have a
'Strict-Transport-Security' with initially low max-age value that will
increase over time.
The plugins implementing new style enhancements are responsible of handling
the saving of configuration checkpoints as well as calling possible restarts
of managed software themselves. For update_autohsts method, the installer may
have to call prepare() to finalize the plugin initialization.
Methods:
enable_autohsts is called when the header is initially installed using a
low max-age value.
update_autohsts is called every time when Certbot is run using 'renew'
verb. The max-age value should be increased over time using this method.
deploy_autohsts is called for every lineage that has had its certificate
renewed. A long HSTS max-age value should be set here, as we should be
confident that the user is able to automatically renew their certificates.
c O � dS )a�
Gets called for each lineage every time Certbot is run with 'renew' verb.
Implementation of this method should increase the max-age value.
:param lineage: Certificate lineage object
:type lineage: certbot.interfaces.RenewableCert
.. note:: prepare() method inherited from `interfaces.Plugin` might need
to be called manually within implementation of this interface method
to finalize the plugin initialization.
