Once a network is determined to have partial connectivity, it
cannot go back to full connectivity without a disconnect. This
is because NetworkMonitor can only communicate either
PARTIAL_CONNECTIVITY or VALID, but not both. Thus, multiple
validation results allow ConnectivityService to know the real
network status.

Delete the unused NetworkManagementService API for set/remove

framework now use the same set of permission constant when communicate

Currntly, keepalive slot is released when stop() is called. Next
starting keepalive can use the same slot number while previous
keepalive is still stopping. When the previous keepalive is
stopped, the incoming as will be processed by the new keepalive.
This change release keepalive slot after the result of stopping
has returned. Thus, newly created keepalive cannot allocate the
same slot number while lower layer is still processing stop event.
This change also disable flaky assertions that are caused by
test port has been occupied by other process.

Currently, strict mode private DNS does not work on VPNs because
NetworkMonitor does not validate VPNs. When a VPN connects, it
immediately transitions to ValidatedState, skipping private DNS
hostname resolution.
This change makes NetworkMonitor perform private DNS hostname
resolution and evaluation even on VPNs.
In order to ensure that the system always immediately switches to
the VPN as soon as it connects, remove the unvalidated penalty
for VPN networks. This ensures that the VPN score is always 101
and the VPN always outscores other networks as soon as it
connects. Previously, it would only outscore other networks
when no-op validation completed.

This reverts commit bdf7048571.
Reason for revert: Adds dependency between IpSecService and
ConnectivityService may lead to future deadlock
problems. Uses a simpler approach instead,
hence the solution is not needed.
See aosp/954040.

The onUnavailable semantics promise that it is equivalent to calling
the unregister callback method. But - it doesn't unregister the callback
allowing it to be reused. Fixed.
Additionally, modified the unregisterNetworkCallback method to not fail
on duplicate unregistration (since a callback could now self
unregister). Instead simply print a log.
