Start_color setting is set to UNDEFINED when creating meter object that
is color aware.

This patch adds the support of meter action for yellow meter policy
flow, so can use meter action for both green and yellow policy flows
in meter hierarchy.
Currently must use the same meter within one meter policy. Packets
passing green/yellow policy flow will have previous meter color of
green/yellow in subsequent meter.

When a hierarchy meter is shared by other ports, it's needed to iterate
all meter policies in hierarchy to create tag rules, to set packet with
next meter ID, which will be used by related meter drop count.
This patch adds the tag rule for yellow support in hierarchy, so both
green/yellow policy flows can set the correct meter ID.

Yellow meter action support is added in meter hierarchy validation.
If one color uses meter action, the other can only use NULL action
or the same meter action. And only shared meter is supported.
