Adds a call to get user total count of licenses. Also corrects one test ID which i hope doesn't break E2E tests (although it should if it does, ha)

This fixes a perf regression in #4456
Context:
URL cache only needs a subset of drive item properties while doing delta queries. See https://github.com/alcionai/corso/pull/4074 for details. Changes in #4456 were applying the default item property set for all delta enumerator consumers including URL cache. This PR fixes the memory regression.

This reverts commit c3f94fd7f76f377e4728c715abbb8c7846e9fb25.
The specified commit is working fine for CI and development, but contains performance
degredation (solved in a follow-up pr) that we want to avoid for the next release. This
rever is temporary, and the changes will be re-instated after release.

Drive pager usage currently showcases strong coupling between two layers: drive collection logic processing and drive api. This PR separates that coupling by moving the full item enumeration process into the
API, and letting the collection logic process the
results. This acs as both a simplification of complex code, and a clearer separation of ownership between the two layers.
A detrimental side effect of this change is that drive item enumeration has moved from page-streaming
(ie: each page is fully processed before moving on to the next) and onto batch processing (ie: all items are stored in memory and processed in a single pass). Acknowledging that this is an unacceptable regression, a follow-up PR will appear shortly with better handling for stream-processing enumeration from the API layer as a standard part of the pattern for all pager
implementations.

Also return mod time when available if
getting the set of added and removed
items. This will be leveraged in later
PRs to implement kopia assisted
incrementals for exchange
Does not change any logic in
collections right now, just adds the
fields to be returned
Also adds an additional return value
denoting if the mod times are expected
to be valid. This is required because
events delta cannot return mod time

<!-- PR description-->
This PR optimizes memory & cache refresh time for URL cache. The cache only makes use of a small subset of drive item properties, namely ID, deleted, file, folder, content download URL. We have found that reducing the number of query properties has a sizable impact on corso mem usage. This is especially relevant for large scale backups.
See below graph for a comparison between original delta queries & mod. Note that this is with corso instrumentations to show comparisons side by side in the same run.
- Reading this graph
- We are doing 3 orig delta queries followed right after by 3 mod. Vertical lines are delta query spans.
Originally, this investigation was done to improve mem usage for scale backups. But we also found that url cache delta query time drops by 22% with this PR. This is because we are now transferring & processing fewer bytes.

populates the item collision cache generators for all exchange data types. Next we'll use these to compare the items being restored for collision before making post requests, by populating this cache at the top of each collection restore process.

some renaming, mostly refactoring the configuration (select and header declaration for each query) by combining the consts.go and query_param.go file into config.go, and making a more composable set of funcs and consts.
