Add flag to generate backup filenames in UTC

[StrayCatDBA]

Filename tokens are currently based on local time. Add a parameter '@UseUTC bit' that bases tokens on UTC time.

This would allow easier integration of the Backup Solution into custom Log Shipping setups as sqllogship.exe uses the filename to determine restore latency.

There is another similar request, #839

I am looking at implementing this.

I am thinking about calling the parameter @TimestampTokensInUTC to make it more clear that it will only affect the tokens, not the logging.

I have a test version. https://github.com/olahallengren/sql-server-maintenance-solution/pull/840

You can pass a parameter like this: @TokenTimezone = 'UTC'

This has been released.
