Revert "Fix tiflash not start with newest nightly PD (#902)"

[lucklove]

This reverts commit 402079d.

We should reverts #902 because it introduced an issue:
#1279

BTW, PD itself fixes #888 in tikv/pd#3163
So we don't need #902 anymore with recently released PD.

However, after revert #902, TiFlash with old PD (before #3163) may not work with tiup-playground

What problem does this PR solve?

tikv/pd#3163 only appears on v5.0.0-rc, v5.0.0-nightly and master of PD, so none of v4.x versions have that fix applied. I think we need to add version check instead of revert it back.
