I solved this issue. I modified service script and it starts and stops in a
proper way. So each command must have own line ExecStart, cannot use &&.
Also `enable` was not working cause needs to put service file to
/lib/systemd/system/wpa_supplicant_my.service and then generate a link.
This is how to make service works:
# cat /lib/systemd/system/wpa_supplicant_my.service
[Unit]
Description=Start WPA Supplicant and Dhclient
After=network.target
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/wpa_supplicant -B -i wlp1s0 -c
/etc/wpa_supplicant/wpa_supplicant.conf
ExecStart=/sbin/dhclient wlp1s0
ExecStop=/usr/bin/killall -q wpa_supplicant
ExecStop=/usr/bin/killall -q dhclient
#TimeoutStartSec=5sec
[Install]
WantedBy=multi-user.target
# systemctl link /lib/systemd/system/wpa_supplicant_my.service
# systemctl start wpa_supplicant_my.service
# systemctl enable wpa_supplicant_my.service
After reboot I have wifi.
# systemctl status wpa_supplicant_my.service
● wpa_supplicant_my.service - Start WPA Supplicant and Dhclient

The next question is: How to watch if wifi is broken and down and then make
my service restarts?
