FS-9319 [mod_dptools] Support "both" in clear_digit_action

Add support for "both" as target parameter to clear_digit_action.
CDA previously only supported target values of:

	"", "self" or "peer"

CDA Behaviour now corresponds with documentation.

For example, the follow will work as expected:

	<action application="clear_digit_action" data="all,both"/>
