Bug fixes and improvements related to device configuration and monitoring

Deploy scripts:

• Added script qdb.sh to deploy QuestDB
• Updated deploy of TeraFlow dependencies in all.sh
• Updated deploy of Monitoring and Grafana in tfs.sh
• Added generation of secrets for QuestDB
• Minor comment typos and cosmetic improvements

Manifests:

• Added manifest for QuestDB deployment
• Extracted QuestDB from Monitoring manifest
• Polished manifest for Monitoring component

Context component:

• Added logic to add devices to default context/topology by default

Device component:

• Added update of endpoint monitor resources with UUIDs
• Added statement to ignore empty of not-found config rules from drivers
• Minor debug helpers in Monitoring-related logic

Device component - Emulated driver:

• Corrected reg-ex to identify endpoints from interface resource keys

Monitoring component:

• Removed unneeded initialization of Device client
• Added mapping of UUIDs to names for samples stored in QuestDB
• Improved management of device events
• Corrected unitary tests
• Cosmetic changes

Service component:

• Added helper methods to check endpoints
• Updated service handlers to use new helper method
• Corrected service handlers to use endpoint name from devices instead of internal endpoint UUID when composing rules for devices
• Removed unneeded log messages

WebUI component:

• Improved name of drivers in AddDevice form
• Corrected variable eclipsation in add device logic
