Fix find blob by tag

[rafamerlin]

There were 2 issues in here, one is that the API version got updated recently and that caused the response to be different than the one expected so querying blobs by tag wasn't working. I believe the version that the current main code has is the response for when we query with x-ms-version: 2019-12-12, however, we're now sending our requests with x-ms-version: 2022-11-02 which caused this to completely break.

Another item was when we add multiple tags to the where expression, that was failing because of the way the URL was being encoded and that doesn't seem to be accepted by Azure REST API.

I've been using a workaround branch that was still using the old API for quite a while without any issues with this URL fix, related to this issue I raised a while ago #1284

The error seems to have changed on the new API version as without the make_url_compatible_with_api if we query anything with more than 1 tag in the filter we get this error:

<?xml version="1.0" encoding="utf-8"?>

One question I have regarding the extra structs I had to add to have the response matching the new format of the XML for the tag content, do we need that at all? I was wondering if we could just drop the tag content as it doesn't seem like it's being used anywhere. Happy to keep it though in case there's any intention of using it in the future or if we want it for information purposes.

@seanmcc-msft is this a known breaking change to the format?

[rafamerlin]

I took the chance to hook up the MaxResults into FindBlobsByTagsBuilder as it wasn't doing anything, removed the next_marker on the input and change it to Marker to match the ListBlobsBuilder and made the next_marker public on the response so we can actually use it.

@seanmcc-msft is there anyone on your team that can review this? It's mostly service-related code.

@jaschrep-msft @vincenttran-msft @jalauzon-msft please take a look.

General note, requiring %20 instead of + as the proper encoding for a space character is service-wide. Any URL encoding done by the library for storage requests needs to do this. Probably beyond the scope of this PR, but good future reference.

main branch has been moved to legacy. Retargeting some old PRs.
