[PATCH 35/37] autofs-5.1.2 - capture cache option and its settings during parsing

[Ian Kent <raven@themaw.net>]

The amd map format parser was not aware of the optional sync
parameter of the cache option.

Make the parser aware of the sync option and capture the cache
option and its settings during map parsing.
