Currently it's hard to say which ovsdb process is which, we can
only guess based on the process pid. Look deeper into the process
command line arguments and determine the name based on the name
of a pid file or a name of the python script.
For example:
Before:
ovsdb-server-ovn-central-az0-1-138
ovsdb-server-ovn-central-az0-1-153
ovsdb-server-ovn-central-az0-1-64
ovsdb-server-ovn-central-az0-1-80
ovn-northd-ovn-central-az0-1-91
ovn-ic-ovn-central-az0-1-184
python3-ovn-tester-50
python3-ovn-tester-51
After:
ovn_ic_nb_db|ovn-central-az0-1|138
ovn_ic_sb_db|ovn-central-az0-1|153
ovnnb_db|ovn-central-az0-1|64
ovnsb_db|ovn-central-az0-1|80
ovn-northd|ovn-central-az0-1|91
ovn-ic|ovn-central-az0-1|184
process-monitor|ovn-tester|50
ovn_tester|ovn-tester|51

We take all the stats and generate sum/mean/max/min graphs per process type as well as an extra graph for all OVN processes together and another one for all OVS processes together. Resulted HTML also contains the peak of the sum of RSS and the peak of the sum of CPU usage for all OVN processes together. Signed-off-by: Ilya Maximets <i.maximets@ovn.org>

This PR adds a new html report
