SqlAgentSettings: New resource proposal

[johlju]

Resource proposal

Suggest adding a resource 'SqlAgentSettings' as per issue #1980. Can probably start with the properties MaximumHistoryRows and MaximumJobHistoryRows from the class JobServer, but would be good to add all other potential properties while at it.

Proposed properties

Property	Type qualifier	Data type	Description	Default value	Allowed values
InstanceName	Key	String	Specifies the name of the SQL Server instance to enable the protocol for.	None	None
MaximumHistoryRows	Write	UInt32	Specifies the maximum number of rows the job history log should allow.	None	None
MaximumJobHistoryRows	Write	UInt32	Specifies the maximum number of job history rows to allow for a job.	None	None

Special considerations or limitations

Can probably re-use code from the DSC Resource SqlAgentAlert that uses the same class.
