docs: Adding a multivariate anomaly detection sample notebook

[yalaudah]

SynapseML v0.9.5 added support for multivariate anomaly detection. Here's a sample notebook that hopefully helps demonstrate this capability.

You can view the rendered version of the notebook here.

Note: Please let me know where I can upload the sample.csv file I'm using in the notebook. I've seen other notebooks in the repo use wasbs://publicwasb@mmlspark.blob.core.windows.net/iot but I don't have access to upload any file there.

[yalaudah]

I just updated the URL of the sample CSV to point to wasbs://publicwasb@mmlspark.blob.core.windows.net/MVAD/sample.csv.

Thanks @serena-ruan !

Hey @yalaudah, could you update that first two cells of getting anomaly_key and connectionString to something like this notebook (https://github.com/microsoft/SynapseML/blob/master/notebooks/features/cognitive_services/CognitiveServices%20-%20Overview.ipynb)

Just anomaly_key and connectionString though. Thanks!

[serena-ruan]

Also, after you address the above comment, please delete this spark creation part:

spark = pyspark.sql.SparkSession.builder.appName("MyApp")
.config("spark.jars.packages", "com.microsoft.azure:synapseml_2.12:0.9.5")
.config("spark.jars.repositories", "https://mmlspark.azureedge.net/maven")
.getOrCreate()
We don't need this anymore, and we will install the corresponding version automatically during tests; for customers, they should follow the guidance in website installation section to install the package.
(Sorry I'm leaving comments like this because the notebook doesn't render correctly on my side)

[yalaudah]

Thanks @serena-ruan! I've updated the notebook to address the two comments above.

Hey @yalaudah thank you so much for this PR. I gave you access to queue builds with /azp run.

[serena-ruan]

Hi @yalaudah For the website to successfully render the notebook, I suggest you sending over the image to me and I could upload it to the storage account for you, then we just render it with a link. BTW, I should have fixed that databricks key error, and this image stuff should be our last step to get this PR in :)

[yalaudah]

Thanks @mhamilton723 and @serena-ruan!

@serena-ruan, I've sent you the image, please let me know if there is anything else I can help with.

@yalaudah this looks like an error due to secrets not being in databricks env. i added and requeued
