Overridable GetConnectionString method in SqlSessionStateProviderAsync

[chenglidev]

Hi,
I am raising this issue because I was going to make a class based on SqlSessionStateProviderAsync to customize connection string.
But I couldn't do that because GetConnectionString method is not overridable in SqlSessionStateProviderAsync.cs.
Would you please consider making it overridable?
That will be really grateful.
Thanks in advance.
