metad is crashed after upgrade from v1

[HarrisChu]

refer vesoft-inc/nebula#3179

https://github.com/vesoft-inc/nebula/blob/master/src/daemons/MetaDaemon.cpp#L203

1. when upgrade from v1 to v2, should also copy share/resources/date_time_zonespec.csv
2. if we don't copy this file, after upgrade to v3, metad would be crashed.

just update doc, transfer this issue

[HarrisChu]

for rpm upgrade, it will copy this file automatically.
just info users when he uses a tgz package to upgrade.
