Indeed the package had been slpitted, on Tumbleweed this leads to:

 rpmqpack | grep texconfig
 texlive-latexconfig
 texlive-xetexconfig
 texlive-xmltexconfig

the main part which originates from former TeTeX head been moved to

 texlive-tetex

For TeXLive 2017 on Leap 15.1 it should be enough to ask zypper

 sudo zypper se revtex
 Loading repository data...
 Reading installed packages...

 S | Name                | Summary                             | Type   
 --+---------------------+-------------------------------------+--------
   | texlive-revtex      | Styles for various Physics Journals | package
   | texlive-revtex-doc  | Documentation for texlive-revtex    | package
   | texlive-revtex4     | Package revtex4                     | package
   | texlive-revtex4-doc | Documentation for texlive-revtex4   | package

and install them to make any physicist happy ... I'm also suggest packages like

 sudo zypper se texlive-ams
 sudo zypper se texlive-boldtensors
 sudo zypper se texlive-astro
 sudo zypper se texlive-physics

if a specific style is missed it is possible to do a search like

 sudo zypper wp 'tex(amstex.sty)'

works also for fonts or better the font descritptions

 sudo zypper wp 'tex(t1uzc.fd)'
