Improve DHCP IP address parsing speed for journal

[JSCU-CNI]

This PR aims to improve DHCP parsing logic introduced in #550. Unfortunately the previous approach makes interactive commands such as target-info slow. We have opted to only parse the first 10000 journal log messages for DHCP IP address leases by default. This can be extended with the flag --dhcp-all.

Hi @Horofic could you take a look at this PR? This fix makes sure target-info does not take up to two hours to complete :)

It also seems like to the test_ips_dhcp now fails.

Those should now be fixed!
