Add support for SUSE Linux Enterprise Server 12

[ellbosch]

SLES 12 is supported on both SQL Server and .NET core. It is recommended that mssql-cli adds support for this platform as well.

0.15.0 is the last supported release for SLES 12.

Not sure what this means:

0.15.0 is the last supported release for SLES 12.

But it doesn't look like it's working (seems to be available on the sles 12 msft repos)

Retrieving package mssql-cli-0.15.0-1.el7.x86_64

Looks like this is the rhel package uploaded to the sles repos.

Could we get one for sles12 and sles15?
