fix healthcheck timeouts and ut8 coercion

this commit fixes two bugs and adds regression tests.

when getting healthcheck values from an image, if the image does not
have a timeout defined, this resulted in a 0 value for timeout.  The
default as described in the man pages is 30s.

when inspecting a container with a healthcheck command, a customer
observed that the &, <, and > characters were being converted into a
unicode escape value.  It turns out json marshalling will by default
coerce string values to ut8.
