Draw curve for the trial

[kerthcet]

What would you like to be added:

We have metrics stored here

alphatrion/alphatrion/metadata/sql_models.py

Lines 106 to 116 in 7e245d2

	class Metric(Base):
	__tablename__ = "metrics"
	uuid = Column(UUID(as_uuid=True), primary_key=True, default=uuid.uuid4)
	key = Column(String, nullable=False)
	value = Column(Float, nullable=False)
	project_id = Column(UUID(as_uuid=True), nullable=False)
	trial_id = Column(UUID(as_uuid=True), nullable=False)
	run_id = Column(UUID(as_uuid=True), nullable=False)
	step = Column(Integer, nullable=False, default=0)
	created_at = Column(DateTime(timezone=True), default=datetime.now(UTC))

Once the trial is finished, we should able to draw the curve for the trial based on different metric name.

Why is this needed:

Completion requirements:
