Remove some duplicated member functions in Context

[JinheLin]

Enhancement

Some member functions in Context are duplicated.

    DatabasePtr getDatabase(const String & database_name) const;
    DatabasePtr getDatabase(const String & database_name);
    DatabasePtr tryGetDatabase(const String & database_name) const;
    DatabasePtr tryGetDatabase(const String & database_name);

    Databases getDatabases() const;
    Databases getDatabases();

Hey @JinheLin, I think I may have trouble understanding the issue, could you please clarify in which way the methods are duplicated? Do you mean remove the non-const version, or remove Context::getDatabase and only use Context::tryGetDatabase ?

Removing the non-const version is enough and there should be no effect on other code. @junaire
