c78bcda461 test-network: add test for sysctl watch 
Add a NetworkdSysctlTest class which ensures that networkd correctly
complains when a sysctl file it's handling has been changed externally.

21d9eeb5e6 networkd: Replace existing objects instead of doing nothing if they exist 
Currently, if for example a traffic control object already exist, networkd
will silently do nothing, even if the settings in the network file for the
traffic control object have changed. Let's instead replace the object if it
already exists so that new settings from the network file are applied as
expected.

Fixes #31226

462be8c957 test-network: find routing policy rule by priority 
We usually configure a test rule with a unique priority. Hence, finding
rule by priority reduces the lines of output, and we can debug easily.

Also print short comments on check. That's helpful when the check is
called several times.

936dec4337 test-network: do not pass '[detached]' to 'ip rule del' 
That indicates the interface name in 'iif' or 'oif' cannot be resolved
when 'ip rule' command is invoked. That's natural when networkd fail to
remove rule but the corresponding interface is already removed.
To make not the residual rules interfere subsequent test cases, let's
ignore the flag and actually remove unwanted rules.

01420b2db5 network/ndisc: use router lifetime as one for redirect route 
Previously, we did not set lifetime for redirect route, and redirect
routes were removed only when received a RA from the target address.
Thus, routes that redirect on-link addresses were never removed.

RFCs mention nothing about the lifetime of redirection. But the previous
implementation does not pass the IPv6 Core Conformance Tests.

This makes
- remember all received RAs and manage them by the sender address
  (previously, remembered only one with the highest preference),
- then use the router lifetime as one for redirect route,
- remove redirect route also when the router corresponds to the sender
  address is dropped (previously, considered only target address).

Note, even if we recieve a new RA, we do not update existing redirect
routes. The lifetime of the redirect route is updated only when a new
Redirect message is received.

Closes #32527.
