Flow records : enhancements to UVE

[Hari Prasad Killi]

Add the following to UVE:
- Drop reason
- TCP bits
- agent count of flows

Also, when action == log, always send the flow records (irrespective of flow sampling) and send them with highest priority.

Define "log" and "alert" as a separate actions in schema for policy rules.

This is required so that log/alert can be specified in addition to other
actions like pass and deny. Also remove the currently defined log/alert/drop/reject
as possible action strings under simple-action.

Agent changes to handle "log" as a possible action in ACL rules.

Agent config handling for ACL rules should handle "log" and "alert" as possible actions and store them in AclEntrySpec and AclEntry objects. These new action values will be used during flow policy handling and can be possible actions for flow.
Removed "DROP" and "REJECT" action definitions. Also when a flow was made as short flow, we were marking the action as DROP. Changed this to use "DENY"
Also added UT to verify log action configured in ACL rule gets reflected in flow Action.
