get mdc_time_offset from the mdc status website
mdc status website: https://ldas-jobs.ligo.caltech.edu/~patrick.brockill/llstatus-K1O3ReplayMDC/index_auto_reload.html
Currently, we provide the mdc_time_offset
in the config file from the status website.
This number gets updated every month at the beginning of a new mdc. Ideally, the cli should read the number from the webpage so that we don't need to update this number in the gwcelery.
