Adding sr.strings file and removing hard-coded strings (#52)

* Strings sweep for connection service

* String sweep for credentials service

* String sweep for hosting

* String sweep for query execution service

* String sweep for Workspace service

* Renaming utility namespace to match standards

Renaming Microsoft.SqlTools.EditorServices.Utility to
Microsoft.SqlTools.ServiceLayer.Utility to match the naming changes done a
while back. Also renaming them on the files that use them

* Namespace change on reliable connection

* Adding the new resx and designer files

* Final bug fixes for srgen

Fixing flakey moq package name

* Removing todo as per @kevcunnane

* Adding using statements as per @llali's comment

* Fixing issues from broken unit tests

Note: This feature contains changes that will break the contract for
saving as CSV and JSON. On success, null is returned as a message instead
of "Success". Changes will be made to the vscode component to handle this
change.

+# String resource file 
+#
+# When processed by the String Resource Tool, this file generates
+# both a .CS and a .RESX file with the same name as the file.
+# The .CS file contains a class which can be used to access these 
+# string resources, including the ability to format in 
+# parameters, which are identified with the .NET {x} format
+# (see String.Format help).  
+#
+# Comments below assume the file name is SR.strings.
+#
+# Lines starting with a semicolon ";" are also treated as comments, but
+# in a future version they will be extracted and made available in LocStudio
+# Put your comments to localizers _before_ the string they apply to.
+#
+# SMO build specific comment
+# after generating the .resx file, run srgen on it and get the .resx file
+# please remember to also check that .resx in, along with the 
+# .strings and .cs files
