Bump UP Version to 1.0.0

[franklinselva]

Closes #38

I have bumped the UP dependency to 1.0 and adapted the related changes.

• One option that has been removed from the test cases during this transition is the creation of the fluents with RealType parameters

# Using UP 1.0.0
from unified_planning.shortcuts import *
some_param = RealType(0,100)
f = Fluent("robot", RealType(0,100), param=some_param)
"""
Raises

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/lib/python3.8/site-packages/unified_planning/model/fluent.py", line 82, in __init__
    raise UPTypeError(
unified_planning.exceptions.UPTypeError: Parameter real[0, 100] param of fluent robot has type real[0, 100]; fluents parameters must have finite domains.
"""

• I have relaxed the versions for the up planners that were available previously. From now, engines can be installed using pip install "up-esb[engines]"
• I have also bumped the version of up-esb to 0.1.0

Commented out on purpose? Seems fine for an optional dependency.
