This method was defined on Gitlab::Database and forwarded the call to an
instance of Gitlab::Database::Connection. Upon closer inspection it
turned out this method isn't used anywhere, nor is it documented. As
such we remove it in this commit, as there's no point in keeping it
around.

This module contained various methods that were forwarded to
Gitlab::Database::Connection. This commit removes these wrappers in
favour of using Gitlab::Database.main instead. This is done to make it
explicit what database connection should be used.

Date pickers emit Javascript Date instances and
these get converted to datetime strings with timezone info.

Ex. a user in UTC+9 timezone picks some date (say July 1).
The underlying Date object gets converted to a string
that uses UTC+0 as the default timezone and the date may
change becuase of this conversion:

'2021-07-01 UTC+9 Korean Standard Time'
=> '2021-06-30T??:??:??Z'
