Discover Azure Databases - UI part

User story:

• When I need to add Azure related DB for the monitoring I need to be able to enter Azure related credentials in PMM UI (add Instance) So I can see the list of all DB existed in the Azure account and processed with Adding them to PMM for monitoring

UI/UX:
TBD
something related to :

Acceptance criteria

• User can enter credentials: AZURE_CLIENT_ID, AZURE_CLIENT_SECRET, AZURE_TENANT_ID, AZURE_SUBSCRIPTION_ID click discovery and see the list of DB services possible monitor by PMM
• List of DBs should contain: Name, DomainName, resourceGroup, Type, Version, Location (port is unavailable - check if standard port works)
• The user is able to select a DB from the list and proceed to a screen to fill more details to start to monitor it by PMM.
• On the screen of Add remote MySQL (PostgreSQL/MariaDB) Instance, the user can see and edit the next fields (filled in or empty):
  • DomainName - filled in
  • Service Name - default DomainName
  • Port - default for DB type: 3306, 5432 - check if it works - ports does not return with selected resource discovery
  • user - filled in by concatenating "<administratorLogin>@<name>"

• • Password - empty
  • Labels
    • Region - repopulated by location

• • • Environment - filled in by tags.environment
    • Do we need fill in any other labels?
    • Custom labels empty
  • Additional option - need additional investigation 
• User able to do all operations using Azure and PMM UI only
• The Discovery process works for:
  • Azure Database for PostgreSQL
  • Azure Database for MySQL
  • Azure Database for MariaDB  - need an additional investigation - as it stays separate from "standard" Azure DB - and its cost does not encourage to do many experiments. 

Here is a screenshot of adding Azure Monitor as a datasource

Also Resource group is required.
It's not clear if it has to be discovered automatically or added as new instance each time with whole list of *ids.

Out of scope:

• any Azure SQL related discovery

Suggested implementation:

•  TBD

Risks:

• Discovery and monitoring of MariaDB
• How to form DSN
• TLS
• **

How to test:

1. Create DB on Azure
2. Genarates credentials.
3. Discover from grafana
4. Add to monitor
5. See matrics on garafana dashboard.

More detailed TBD
