[Modules] Updated VNET Gateway to reference PIP module

[lsnoddy]

Description

Refactored the virtualNetworkGateways module to reference the publicIPAddresses module instead of implementing a resource:

• Removed virtualGatewayPublicIP_lock resource since managed by PIP module
• Removed virtualNetworkGatewayPublicIp_diagnosticSettings since managed by PIP module
• Removed publicIpDiagnosticsLogsSpecified and publicIpDiagnosticsLogs variables as no longer required

Added dnsSettings property to publicIPAddresses module since VNET gateway used one of the parameters (domainNameLabel)

• Added optional parameters domainNameLabel, fqdn, reverseFqdn
• Added dnsSettings in properties

@lsnoddy .. shouldn't the gateway documentation now include the public IP address module in the Cross-referenced modules section?

Example from another module:

Actually true. @lsnoddy, please run the ReadMe generation for that module too.

See other comments: Readme Generation for VNET GW module wasn't run yet.
