feat: improve query modification

[karl-power]

Changes

• Implements DataSourceWithQueryModificationSupport on the Datasource, adding the getSupportedQueryModifications method which returns:

['ADD_FILTER', 'ADD_FILTER_OUT', 'ADD_STRING_FILTER', 'ADD_STRING_FILTER_OUT'].

• This change enables the Logs Popover Menu shown in screenshot below, which has both the ADD_STRING_FILTER and ADD_STRING_FILTER_OUT options.
• Adds new filter operators ILIKE and NOT ILIKE to be used with this new filter options.
• When selecting either of the new filters from the popover menu, no key is provided in the call to modifyQuery, so we use the log message column for the filters, getting that from the column hint.
• Only works in query builder mode, like the existing ADD_FILTER and ADD_FILTER_OUT modifications
