Kevin King 90b3145e92 Updated excel_knowledge_source.py to account for excel files with multiple tabs. (#1921) ...

* Updated excel_knowledge_source.py to account for excel sheets that have multiple tabs. The old implementation contained a single df=pd.read_excel(excel_file_path), which only reads the first or most recently used excel sheet. The updated functionality reads all sheets in the excel workbook.

* updated load_content() function in excel_knowledge_source.py to reduce memory usage and provide better documentation

* accidentally didn't delete the old load_content() function in last commit - corrected this

* Added an override for the content field from the inheritted BaseFileKnowledgeSource to account for the change in the load_content method to support excel files with multiple tabs/sheets. This change should ensure it passes the type check test, as it failed before since content was assigned a different type in BaseFileKnowledgeSource

* Now removed the commented out imports in _import_dependencies, as requested

* Updated excel_knowledge_source to fix linter errors and type errors. Changed inheritence from basefileknowledgesource to baseknowledgesource because basefileknowledgesource's types conflicted (in particular the load_content function and the content class variable.
